Context There are two things that can be acknowledged when going over the previous phase. They are goals and features. Now, it comes to the second phase, analysis. In this phase, the tech stack used for development should be determined. Before figuring out the tech stack, the components of this application should be recognized. Usually, a web application would have three parts, namely a front-end application, a back-end application, and a database. In this phase, the tech stack for these three components would become clear. Currently, many websites are developed with React, which is a JavaScript library for web development. It could be an ideal option for this project. However, React does not have built-in tools, like routing and state management. It might make the learning curve steeper…  ( 7 min )

Over the past few months, I’ve been knee-deep in mobile development, not chasing trends, but chasing sanity. My goal? Find the best lightweight framework for building real cross-platform apps without frying my CPU, roasting my RAM, or downloading SDKs heavier than the apps themselves. So instead of the typical fanboy arguments, I actually used all three frameworks: Flutter React Native Kivy ...to figure out which one gets the job done without demanding a space-grade workstation. Here’s the breakdown, battle-tested, brutally honest, and resource-conscious. When I say lightweight, I’m talking about: ✅ Low RAM/CPU usage during dev ✅ Minimal setup time (no 10GB SDKs, please) ✅ Fast learning curve ✅ Doesn’t turn your laptop into a jet engine Framework Language Core Strength Flutter Dart …  ( 7 min )

Contrary to what many tutorials suggest, simply changing the SSH port or installing Fail2Ban is not enough. This documentation shows the exact steps to harden the security of an Ubuntu/Debian server by configuring key-based authentication, disabling insecure defaults, and reducing the attack surface. Author: joaoprd | joaopedrord2001@gmail.com Create a user with sudo privileges: adduser whiterose usermod -aG sudo whiterose The user whiterose will be the only one authorized to connect via SSH after hardening. Public key authentication avoids the use of passwords and is essential for a secure server. This step will be done manually, without using ssh-copy-id.

Problem You are climbing a staircase. It takes n steps to reach the top. Each time you can either climb 1 or 2 steps. In how many distinct ways can you climb to the top? Example 1: Input: n = 2 1 step + 1 step 2 steps def climbStairs(self, n: int) -> int: # if less than or equal to 2 steps, we know there's 1 way or 2 ways. if n end, implementing fibonnaci algoritm n = (n-1 + n-2) for i in range(3, n + 1): step_ways[i] = step_ways[i-1] + step_ways[i-2] return step_ways[n] This problem is basically just the fibonacci sequence, in that to get step 3 upwards, you can take the methods of getting there from the previous two ways and add them together. For example: Think about how you can reach say step 11: If Last step was a single step: So all ways to reach step 10 can lead to step 11 by adding a 1-step jump, so we can add 1 step to all the pre-existing ways to get 10. Last step was a double step: So all ways to reach step 9 can lead to step 11 by adding a 2-step jump, so we can add 2 step to all the pre-existing ways to get 10. note: below n relates to the current step number we're trying to work out: So if we all the ways you got to 10 (n-1) and all ways you got to step 9(n-2) you know all the ways you can get to 11. Cos we can deduce you've got there either by adding 1 or adding 2. So you may have noticed ways = ways(n-1) + ways(n-2) looks familiar, its the same as the Fibonacci sequence Fib(k) = Fib(k-1) + Fib(k-2) Therefore we can simply write this as code -> (i've added comments to explain in code rather than here) As always feel free to drop me a follow on DevTo or twitter/x  ( 6 min )

Problem Given a non-negative integer x, return the square root of x rounded down to the nearest integer. The returned integer should be non-negative as well. You must not use any built-in exponent function or operator. For example, do not use pow(x, 0.5) in c++ or x ** 0.5 in python. Example 1: Input: x = 4 public int MySqrt(int x) { if (x = 2. So we search between 1 and x / 2. Binary Search Mechanics: Pick the middle number mid. Compute mid * mid (cast to long to avoid overflow). If mid * mid == x → return mid (perfect square). If mid * mid x → move right down to mid - 1. Return the last recorded answer because it’s the floor of the square root. By using the Binary Search mechanics, we reduce the numbers needing to be checked can be halved each time, halving the amount of effort needed to find the correct number. As always drop me a follow on DevTo or twitter/x to hear about future articles like this.  ( 6 min )

In most web frameworks (Spring, Django, FastAPI, Axum) the handlers return an object to the framework that will be used to build the response that is sent to the client. However, the Go lang net/http package uses a different approach: the handlers write data directly into the response and have no return value. I believe that this behavior comes from a time that the most frameworks worked with blocking IO and employed optimizations using queues and threads dedicated to process the responses, so your code would return an object describing the response and the framework would put it in the queue to be processed by a thread. With non-blocking IO, there is no need for these optimizations, since the async runtime already takes care of everything related to IO, allowing handlers to write data directly to the response. So, which is better? Return a response or write to the response?  ( 5 min )

Problem Given an integer array nums and an integer val, remove all occurrences of val in nums in-place. The order of the elements may be changed. Then return the number of elements in nums which are not equal to val. Consider the number of elements in nums which are not equal to val be k, to get accepted, you need to do the following things: Change the array nums such that the first k elements of nums contain the elements which are not equal to val. The remaining elements of nums are not important as well as the size of nums.

What is Python? Python is a powerful, high-level, and easy-to-learn programming language that is widely used in software development, DevOps, data science, automation, web development, artificial intelligence, and more. Guido van Rossum, a Dutch programmer, created Python in the late 1980s, He officially released Python 1.0 in 1991. Guido's goal was to make a language that was easy to read and write, allowing developers to express ideas in fewer lines of code. Python emphasizes readability and simplicity, making it a great language for both beginners and experienced developers. Open-Source and Free: Python is free to use and distribute even for commercial purposes. Its source code is publicly available, and a vast global community contributes to its development and improvement. General-P…  ( 6 min )

In the era of large language models, prompt size is power — but also a big cost. TokenSpan isn’t a compression library, it’s a thought experiment — a different way of thinking about prompt optimization. Can we reduce token usage by substituting repeated phrases with lightweight aliases? Can we borrow ideas from dictionary encoding to constrain and compress the language we use to communicate with models? This project explores those questions — not by building a full encoding system, but by probing whether such a technique might be useful, measurable, and worth pursuing. A crucial insight behind TokenSpan is recognizing where the real cost lies: We pay for tokens, not computation. So why not reduce the tokens we send, and let the model handle the substitution? §a means "Microsoft Designer" —…  ( 7 min )

🚨 Why This Matters Without governance, your data platform becomes a ticking time bomb. Data chaos isn’t just about bad reports — it’s about loss of trust, wasted engineering hours, poor decisions, and potential compliance nightmares. And in the AI era, the stakes are even higher. If you’re dealing with duplicate sources, unclear ownership, and no clue who should access what — this post is for you. Business users pulling reports from different tools — all showing different numbers Engineers hard-coding sensitive filters into pipelines to "fix" the output Data analysts unsure whether they're allowed to access a dataset — so they just... do Dashboards showing obsolete or wrong metrics Rows with PII data being exposed without control That’s what happens when data governance is absent or treated as an afterthought. Data governance is the set of practices, roles, policies, and standards that ensure your data is reliable, secure, and used appropriately. It's not just about compliance or regulation. It's about control, trust, and scaling your data strategy. Ownership & Stewardship Every table, dataset, or domain must have an owner Owners are accountable for data quality, documentation, and access Empower stewards to maintain metadata, SLAs, and definitions Access & Security Controls Use RBAC (Role-Based Access Control) Enable Row-Level Security (RLS) for multi-tenant platforms or sensitive datasets Manage access centrally — not via code Example: In platforms like Snowflake or Sigma Computing, you can enforce RLS using dynamic attributes like customer_id or region. sql -- Snowflake RLS Example CREATE ROW ACCESS POLICY filter_by_customer AS (customer_id STRING) RETURNS BOOLEAN -> CURRENT_ROLE() IN ('CUSTOMER_VIEWER') AND customer_id = CURRENT_USER();  ( 6 min )

Importing pet accessories into Canada—such as dog collars, toys, grooming tools, and pet beds—requires a clear understanding of the duties and taxes imposed at the border. Whether you're a small e-commerce seller or a pet product distributor, knowing how to classify your goods, calculate fees, and comply with Canadian customs regulations can save you both time and money. When pet accessories cross into Canada, they are subject to two main types of fees: import duties and sales taxes. Import duties are based on the Harmonized System (HS) code classification of the goods, their country of origin, and their declared value. Taxes usually include GST (Goods and Services Tax) and may also involve PST (Provincial Sales Tax) or HST (Harmonized Sales Tax), depending on the province where the goods …  ( 6 min )

Introduction If you've been working with ASP.NET Core and haven't encountered Areas yet, you're not alone. Despite being a powerful organisational feature, Areas are often overlooked in tutorials and beginner resources. This oversight leads many developers to create convoluted controller hierarchies and strange architectural patterns that Areas were specifically designed to solve. I've seen projects where developers create "super controllers" or awkward folder structures trying to achieve what Areas provide out of the box. Let's fix that. Areas are a feature in ASP.NET Core that allow you to partition your web application into smaller functional groups. Each area represents a distinct section of your application with its own set of controllers, views, and models. Think of them as mini-MV…  ( 7 min )

What is a Task in Swift? Think of a Task as a box that contains some work your app needs to do. In Swift's async/await world, when you write async functions, you're creating these boxes of work that can run at the same time. func parentFunction() async { // This is the main task (parent) async let child1 = childFunction1() // Creates a child task async let child2 = childFunction2() // Creates another child task await [child1, child2] // Wait for both children to finish } The parent task creates child tasks, and they all form a family tree.

Let's Start from the Beginning About a month ago, the whole vibe coding trend really caught my attention. Everyone was talking about it, everyone. Blog posts were all over the internet, LinkedIn was full of non-technical folks suddenly turning into “builders,” claiming they could create full-blown applications without knowing a thing about software engineering or coding. At first, I didn't pay much attention. I figured it was just another passing trend, like Web3, the metaverse, or Windows Phone (which, to be fair, I actually liked, don't judge me). But then I started seeing even seasoned software engineers showing off their vibe coding setups (I know, it sounds weird), comparing different LLMs and workflows.

With the introduction of Signals in Angular, state management has become much clearer, more maintainable, and predictable. Thanks to primitives like signal(), computed(), and effect(), you can model and derive data effectively while keeping dependencies between different parts of the state under control. However, updating deep values of a Signal is not as straightforward, often requiring manual interventions on the parent state. To address this need, the Angular team is currently developing a new Signal primitive that allows reactive access and modification of deep properties within another Signal: Deep Signal. In this article, you'll explore what Deep Signals are, how they work, and why they can help simplify the code in your Angular applications. Let’s consider an application that manage…  ( 10 min )

lodash It is a JavaScript utility library that is fully compatible with React Native. It provides a large number of helpful utility functions to make working with arrays, objects, numbers, strings, etc., easier and more consistent. Do We Really Need Lodash? Not always. But for more complex operations like deep cloning, sorting, or throttling, Lodash saves time and reduces bugs. Performance Tips Lodash is huge if you import the full library. Always import specific methods like lodash/isNumber to avoid bloating your bundle. because if you do this: import _ from 'lodash'; ✅ It works. ❌ But it includes the entire Lodash library, even if you only use isNumber(). That adds ~70 KB+ to your bundle. Bloating your bundle” means adding unnecessary code that's never used but still included in your final app. Tools like babel-plugin-lodash help optimize it automatically. babel-plugin-lodash This Babel plugin automatically rewrites your imports like this: import { isNumber } from 'lodash'; import isNumber from 'lodash/isNumber'; Final Thoughts Lodash is still useful just use it wisely.

Verifying your Git commits builds trust and shows authenticity. On GitHub, verified commits display a “Verified” badge to signal they were signed with a trusted GPG key. Here’s a step-by-step guide to setting it up on macOS using the GPG Keychain app. Prerequisites macOS GPG Suite installed (includes GPG Keychain) Git installed GitHub account Step 1: Generate a GPG Key Using GPG Keychain Open GPG Keychain Click the “New” button. Fill in your: Name (should match your GitHub name Email (must match the email you use in your Git commits) Key Type: RSA and RSA (default) Key Length: 4096 bits (recommended) Expiration date: Optional Click “Create Key” and wait until the key is generated. Step 2: Export Your Public Key Right-click your new key and select “Copy”. Step 3: Add the GPG Key to GitHub Go to GitHub → Settings → SSH and GPG Keys. Click “New GPG Key”. Paste the copied key (or the contents of your exported .asc file). Click “Add GPG Key”. Step 4: Configure Git to Sign Commits Find your GPG key ID: gpg --list-secret-keys --keyid-format LONG sec rsa4096/ABCD1234EFGH5678 .. git config --global user.signingkey ABCD1234EFGH5678 Set Git to use GPG (this path may vary): git config --global gpg.program $(which gpg) Step 5: Make a Signed Commit git commit -S -m "Your signed commit message" Push your code to GitHub. If everything is set up correctly, GitHub will show a Verified badge next to your commit. If you want to learn how to get GitHub achievements!

If you’ve ever wanted to build a SaaS, you’ve probably heard this story: Developer spends 6 months coding a brilliant idea. This happens because most devs build in the dark. They overcomplicate, overengineer, and underlaunch. But 2025 is a different game. Thanks to software as a service in cloud computing, a solo developer can now launch a profitable app in just 10 days — without managing servers, hiring a team, or burning a hole in their wallet. In simple terms: SaaS (Software as a Service) is an app hosted in the cloud, accessed by users through a browser. Cloud computing means someone else handles servers, scaling, and updates — you just build features and collect revenue. Why this matters in 2025: 🚀 Zero DevOps overhead — deploy to Vercel, Supabase, or Render in minutes. 💳 Payments b…  ( 7 min )

Every developer dreams of building something that people actually pay for. The problem? Most SaaS ideas are overbuilt before launch. Most devs spend months coding, polishing, and tweaking… only to see zero customers. And most importantly: They underestimate the speed advantage cloud computing now gives them. If you’ve been sleeping on Software as a Service (SaaS) in Cloud Computing, you’re missing the easiest era to launch. We’re in a moment where one person can create a fully-functional, customer-ready SaaS — from idea to live product — in under 10 days. This post breaks it down: What SaaS in cloud computing actually means in 2025 (and why it’s easier than ever). How Micro‑SaaS flips the script from bloated apps to profitable mini‑tools.

What is javascript? javascript is the world most papular programing language and it is easy to learn. javascript is used to create interactive and dynamic web pages. it is responsible for adding functionality to a website and allows for user interaction with the website's content. VARIABLES:- variales are containers for stroing information or data. example var a=10 var b=20 console.log(a+b) output:20 in the above program a and b are variables,10 and 20 are integers. console.log - it is the function in javascript used to print messages or values to the browser's console mainly for debugging purpose. in javascript variable can be declared in 3 ways. var let const using var keyword- function scope or global scope. var x=10 { var y=20 } console.log(y) output:20 //accessible inside the block. using let ketword- block scope. the let keyword introduced in 2015. the keyword must be declared before use. let keyword can not be redeclared. let keyword have block scope. { let a=10 } console.log(a) output Error: a is not defined // a can't be used here becauce a is the block scope. { let a=10 console.log(a) } ouput:20 // a can be used hear. using const keyword- block scope. in javascript the const keyword is used to declare a constant variable. a constant variable once assinged value cannot be reassinged or redeclared. it provide a way to create variable that are meant to be immutable. const a=10 a=20 console.log(a) output Error:assingnment to constant variable. //const cannot be reassinged  ( 6 min )

We already know what JavaScript is, how it was created, and the keywords we can use while programming using this language. Now we’re getting to know our data types, and how we can make use of the ways JavaScript handles them. By the end of this post, you should be able to understand how JavaScript handles values under the hood and you’ll have the ability to tell them apart at a glance… at least that I hope, so let’s get into it! JS has two both primitive and reference types. Primitives types: string, number, bigint, boolean, symbol, undefined, null. Reference types: object, array, function. You can use typeof function to inspect types, though, be mindful that, sometimes, JavaScript can handle types in every way but a logical one.

Hey DEV 👋 I’ve been building a music-focused side project for quite a while now, and I’d love to share it with you all. 🎵 It’s called Bellino — a free music discovery site I built with: React + TypeScript on the frontend PHP + MySQL on the backend A custom REST API for serving dynamic data YouTube IFrame API for embedded playback Bellino lets users: Explore trending tracks and artists Browse curated playlists by mood, genre, or decade Discover albums that were released on this day in music history Listen instantly, with no login required (though creating an account lets you save playlists and favorites) 🌐 Try it here → https://www.belllino.com/home I've been collecting and organizing music data since 2014 because I genuinely love finding great music — both old and new. Most platforms today are heavily focused on current hits or algorithmic recommendations. I wanted something more personal and playful — a place where you could: Discover random playlists and live charts Explore music by vibe, decade, or release date See what albums dropped on your birthday Dive into other users’ playlists and tastes So I built Bellino to scratch my own itch — and maybe yours too. React (TypeScript) – SPA using basic routing and custom hooks PHP backend – lightweight API with fast JSON responses MySQL – for managing users, charts, playlists, track data CSS Modules – no UI libraries, just styled components YouTube IFrame API – for free and simple embedded playback I’m not monetizing this — it’s just a long-running passion project.

Another day in the life of a developer where the code isn't the hardest part to figure out. Morning started simple enough: install Tailwind CSS. Should be straightforward, right? Wrong. Spent half the day battling mysterious "npx" errors that made absolutely no sense. You know that feeling when you're staring at your terminal, questioning every life choice that led you to this moment? Yeah, that was my Monday morning. Finally got Tailwind running, only to realize I had lectures from 9 AM to 4 PM. Missed attendance in one class because sometimes the universe has a sense of humor. Here's where it gets interesting. Remember that ideathon team I mentioned? Turns out they're "a little tooooo busy" to actually work on our project. I was planning this amazing pitch, thinking we'd create something solid together. Instead, I get the classic "let's do it in 2 minutes" approach. The day ended with me hand-washing clothes in the hostel—no washing machine, just pure hand power. But here's the twist: my wrist, which has been bothering me for weeks, actually worked well. The plan? Learn Figma animations, dive deeper into Tailwind, and tackle React Router. Sounds unrealistic? Probably. But when you're working alone, at least you're only disappointing yourself if things don't go according to plan. The real lesson from today: sometimes the biggest debugging challenge isn't in your code—it's in your team dynamics. And sometimes, the best solution is to refactor your entire approach and go it alone. Time to prove that solo doesn't mean lonely in the development world.  ( 6 min )

MongoDB is a general-purpose database that offers more than just a JSON datastore. It is recognized for its efficient indexing and aggregation capabilities within flexible schemas. The query planner optimizes the aggregation pipeline to filter data early and effectively utilize indexes. It's important to note that some optimizer transformations applicable to tabular data in relational databases may not work the same way with documents. Keeping this in mind helps in understanding why an index is employed or not, as the query planner must ensure consistent results across all possible documents in the flexible schema. As an example, a projection renaming a JSON dotted path before filtering can alter its semantics and hinder index usage. I store customer contact information like this: db.custo…  ( 10 min )

JS Operators: Arithmetic Operators: These operators are used to perform basic mathematical operation on numbers. List of arithmetic operators: let x=10; let y=5 let z=x+y; //15 If a string is added with a number, it will produce concatenation. let x="10"; let y=5; let z=x+y; The value of z will be "105". true+1 = 2 b) Subtraction operator (-) : let x=10; let y=5 let z=x-y; //5 In case of any string value [ex "10"] it will change the string value to integer and perform the subtraction. parseInt(): It is a function in JS which is used to convert string to an integer. let x = "10"; let y = 5; let z = parseInt(x) + y; Output is 15. c) Multiplication operator (*) : let x=7; let y=3; let z=x*y; //21 d) Division operator (/) : It gives the quotient. let x=10; let y=2 let z=x/y //5 e) Modulus operator (%) : It gives the remainder. let x=10; let y=2 let z=x%y //0 f) Exponential operator (**) : let x = 5; let z = x ** 2; //25 g) Increment operator (++) : Post-increment: let i=10; i=i+1; //11 It can also be written as let i=10; i++ ; //11 Pre-increment: let x = 5; let y = ++x; log (x); //6 log (y); //6 Pre-decrement: let j=10; --j; log(j); //9 log(--j); //8 Post-decrement: let x = 5; let y = x--; //4 2) Comparison operators: These are used to compare two numbers and returns a boolean value. Ex: let i=5; let j=7; ++i > --j // 6>6 which is false. Logical operators: Multiple conditions can be combined using logical operators. They use logic to return true or false. List of logical operators: log(5 > 3 && 10 > 2); // true b) logical or (||) - returns true if at least one condition is true and returns false only if both conditions are false. log(5 > 3 || 1 > 2); //true log(1 > 5 || 2 > 4); //false c) logical not (!) - The condition becomes reverse like true becomes false, false becomes true.  ( 7 min )

If you have ever wondered how your favorite websites actually work behind the scenes, welcome to the fascinating world of backend development. While frontend development focuses on what users see and interact with, backend development powers the logic, data, and infrastructure that make the magic happen. In this post, we’ll cover the basics of backend development—what it is, the key components, tools, and how to start your journey. The backend is the “server-side” of an application. It’s responsible for: Handling requests from the frontend Storing and retrieving data from databases Performing business logic (like calculating shipping costs or verifying a login) Serving responses back to the frontend In short, if the frontend is the shop counter, the backend is the warehouse and staff makin…  ( 6 min )

JavaScript Local Storage is a feature that allows you to store data in the user's browser persistently — the data doesn't get deleted when the browser is closed (unlike session storage). Basic Local Storage Methods Store Data localStorage.setItem("username", "Adithi"); Get Data let user = localStorage.getItem("username"); console.log(user); // Output: Adithi Remove a Key localStorage.removeItem("username"); Clear All Storage localStorage.clear(); Store Objects or Arrays Since localStorage stores only strings, you need to convert objects/arrays: let user = { name: "Adithi", age: 21 }; // Save object localStorage.setItem("user", JSON.stringify(user)); // Get object let storedUser = JSON.parse(localStorage.getItem("user")); console.log(storedUser.name); // Output: Adithi  ( 5 min )

This isn't a systematic analysis of StackOverflow's 2025 Developer Survey, it's the random tidbits I found most interesting. (Okay, this was taking way longer than I anticipated, I'm breaking it up into two parts but also, I'm being long-winded. :-P Usually I go back and trim things down but if I don't post this now, I never will). I'd like to see educational degrees split up by area of study. I've been doing this for years and have a B.S. but it's not even tangentially related to coding. It would be great to see these results graphed over time. I appreciate that SO broke out JS and TS as two separate entries, but I'd also love to know what the percentage is when the two are combined. There would be a lot of overlap so it isn't as simple as adding the two percentages together. PostgreSQL d…  ( 9 min )

what is javascript ? It is a programming language of the web pages. It is updated and change both HTML and CSS. It can calculated ,manipulate and validate data. what is javascript variables ? Java script variables is used to the store data values. Java script uses the keywords likes var,let,const to declare variables. what is var ? Only use var if you MUST support old browsers. The var keyword was used in all JavaScript code from 1995 to 2015. Variables declared with the var always have Global Scope. what is let ? The let declaration declares re-assignable, block-scoped local variables, optionally initializing each to a value. The let keyword was introduced in ES6 (2015). what is const ? The const keyword was introduced in ES6 (2015). Variables defined with const cannot be Redeclared. Variables defined with const cannot be Reassigned. Variables defined with const have Block Scope.  ( 5 min )

The Fetch API provides a JavaScript interface for making HTTP requests and processing the responses Using the Fetch API With the Fetch API, you make a request by calling fetch(), which is available as a global function in both window and worker contexts. You pass it a Request object or a string containing the URL to fetch, along with an optional argument to configure the request. The fetch() function returns a Promise which is fulfilled with a Response object representing the server's response. You can then check the request status and extract the body of the response in various formats, including text and JSON, by calling the appropriate method on the response. Here's a minimal function that uses fetch() to retrieve some JSON data from a server: Syntax: fetch(url) .then (res=> res.j…  ( 6 min )

As my friends, family, coworkers, and probably several people on the internet already know: I am a AI skeptic – and I’m not particularly shy about it, either. I’m not really sold on the productivity improvement angle, and I’m especially cautious (and critical) when it comes to using it to create content. I’m routinely underwhelmed by emails, blogs, illustrations, logos, and more that were clearly created without human involvement. As an artist and writer myself, those aren’t things that I, personally, am seeking to replace or automate out in my own life. That said, I also work in tech where AI is (for the time being) borderline inescapable. I also think it’s decidedly lame to write something off without giving it a genuine try. And, if I’m completely honest, I was also just plain curious:…  ( 11 min )

When I build software, I try to make the app remember things. So the user doesn’t have to do the same stuff over and over. Most apps reset everything on refresh or when you come back later. That gets annoying fast. Here’s what I mean: You click the same tab again You re-select your filter or sort You retype the same input or prompt You toggle dark mode every single time You expand the same panel again and again It’s small stuff, but it adds up. And it makes your app feel worse. localStorage to remember things I now save small bits of state in localStorage. Just enough so the app feels more stable and consistent. Here’s what I usually save: Last open tab Dark or light mode Draft input or prompt Filters or sort settings Collapsed/expanded sidebar Dismissed modals or popups (usually the one…  ( 6 min )

Apple just dropped something big — quietly. No flashy launch event, no keynote. Just a powerful new feature in the background: Apple Answers. This post is a follow-up to our earlier explorations on how the AI landscape is rapidly shifting. But this time, we’re looking at what Apple’s stealth strategy really means — and how businesses can prepare. Apple Answers is Apple’s new generative AI feature, designed to deliver fast, accurate responses to user queries — powered by both local and cloud-based intelligence.

Unlike ChatGPT or Perplexity, Apple Answers prioritizes on-device privacy, leveraging Apple Silicon and tight ecosystem control to create…  ( 7 min )

Lately, I’ve been leaning into building small internal tools for my team. Things that aren’t glamorous, but make our process smoother. One of the most useful was a user interview tracker: just a lightweight web app where we could log interview notes, tag them by feature or theme, and revisit them later. I built it in a few hours using React + Gadget, and it’s one of those tools that quietly changed how we work. Why Build One? I didn’t want to build a whole CRM or research platform. Just a place to: Log interview notes (timestamped and associated with a user) Tag entries by themes (like “onboarding friction” or “mobile nav”) Search and filter by tags or date Keep things private but sharable with the team Enter Gadget: Gadget gives you: Built in Postgres DB (via a visual schema editor) Auth (already wired up) File storage (handy if we want to upload transcripts later) Auto generated REST + GraphQL APIs A backend code editor (runs server side, uses JS/TS) Free tier with generous limits All I had to do was hook up a React frontend, and I was off. A Quick Breakdown of the Build Schema setup Auth API Backend logic What Went Wrong (But Not Really) Nested filtering in GraphQL took a minute to figure out. I wanted to get “all interviews tagged with ‘onboarding’ from the last month” and had to poke around a bit to structure the query right. I briefly messed up the permissions config. My own fault, not Gadget’s and accidentally let anyone delete entries. Luckily, their UI makes it easy to review access rules. Styling took longer than it should have (because I fuss over UI too much). But honestly? Nothing broke. I never got stuck debugging some weird auth middleware or tracking down CORS issues. It felt like working downhill. Final Thoughts It’s simple. And it works. And I actually enjoyed building it.  ( 6 min )

Finding the ideal human resources translation software is critical to the health of your organization. Here’s why. Intelligent internal communication means that your training materials, newsletters, memos and emails all convey the same exact meaning and tone–regardless of an employee’s native language. For this reason, it’s critical to refrain from relying on pure machine translation for HR. If you do, you’ll sacrifice the quality of your workplace communication. And this can affect working relationships, cause misunderstandings of policies and agreements and may even lead to lawsuits. Generally speaking, it may negatively affect your organization’s morale or culture. The problem with using a pure machine translation tool (e.g. Google Translate) as your human resources translation software…  ( 7 min )

Introduction I'm Aki, an AWS Community Builder (@jitepengin). Apache Iceberg is one of the emerging open table formats that has gained attention recently. It supports features such as schema evolution, ACID transactions, and time travel. When managing tables based on snapshots, there are many scenarios in development, testing, and production where you want to track or manipulate snapshot histories. As a learning project, I created a CLI tool called iceberg-navigator that lets you inspect snapshot history and details of Iceberg tables on AWS. In this article, I’ll introduce this tool. Easily check the snapshot history of Iceberg tables stored in S3 via the command line. Trace snapshot parent-child relationships to understand version lineage.

I use Asana a lot. I review tasks, leave comments, update timelines, and read through long threads. When I want help from an AI like summarizing updates, writing follow-ups, or planning what is next, I usually have to stop, copy parts of a task into a prompt, and explain the context. I have done that too many times. It always feels clunky and disconnected. Asana MCP fixes this. It connects Claude and Cursor directly to your Asana workspace through Composio, so they can work with your actual tasks, comments, and project data in real time. You don’t need to switch tabs, rephrase anything, or explain what just happened in a thread. In this article, I will show you how to set up Asana MCP and use it to make Claude and Cursor more helpful with your daily work in Asana. Think of MCP as a bridge…  ( 10 min )

The Funding Rate Arbitrage strategy allows you to profit from the unique mechanics of perpetual futures. For developer-traders, this is a perfect use case for building a custom algorithmic bot. Here's how the strategy works and how you can implement it. The Mechanism: The Foundation of the Strategy Exchanges use the Funding Rate to keep the perpetual futures price anchored near the spot price. Funding Rate > 0: Longs pay shorts. The futures price is trading at a premium to the spot price. Funding Rate < 0: Shorts pay longs. The futures price is trading at a discount to the spot price. Your goal is to take a position that allows you to collect this fee while remaining neutral to the asset's price fluctuations.

By Muhammed Shafin P (@hejhdiss) This is Part 2 of our series on rethinking embedded web frameworks. Read Part 1: The Smart, Selective Engine Developers Actually Need for the foundational concepts. While the concept of a selective, multi-engine embedded web framework addresses critical pain points in modern development, the real challenge lies in implementation. How do we make auto-detection reliable? How do we handle engine transitions smoothly? How do we optimize for real-world performance? The answers lie in leveraging modern techniques that go far beyond traditional static analysis approaches. The key to making selective engine loading work reliably isn't perfect detection—it's smart, fast detection with graceful fallbacks. Instead of parsing entire files or complex static analysis, we…  ( 10 min )

Monitoring is great, but alerting is what actually wakes us up. In this post, I’ll show how we built a log-based alerting pipeline using Grafana, Loki, and Promtail, running entirely in containers. Yes, alerts triggered from log patterns, not metrics. This approach is especially useful when monitoring behaviors like rate-limiter violations that may not expose traditional metrics. We were facing a challenge: we implemented a rate limiter in Nginx to prevent abuse, but traditional metrics collection (via Prometheus) couldn't capture rate-limit violations (HTTP 429 responses), because those were handled entirely at the reverse proxy level, not within the app itself. The solution? Log everything. Then alert from logs. Grafana Loki Promtail Nginx (with rate limiting configured) Docker Compose…  ( 9 min )

¿A qué nos referimos cuando hablamos de diseño en desarrollo de software? Cuando hablamos de diseño en el desarrollo de software, no nos referimos a dibujar interfaces o hacer diagramas bonitos. En este contexto, diseñar es programar. El diseño se manifiesta en cómo estructuramos el código, cómo distribuimos responsabilidades, cómo nombramos, cómo pensamos en la mantenibilidad, la extensibilidad y la claridad del sistema. Pero también incluye decisiones más amplias como cómo estructuramos el proyecto, cómo organizamos carpetas, módulos y dependencias. El modelado tiene que ver con representar el dominio del problema. Es la forma en que interpretamos y trasladamos el mundo real —o una parte de él— a estructuras que puede entender una máquina. Modelar es preguntarse: “¿Cómo represento …  ( 9 min )

Un poco de contexto En un contexto en el que la inteligencia artificial gana cada vez más terreno, si queremos destacarnos como desarrolladores —y que la IA sea un potenciador de nuestras habilidades y no “algo que nos va a quitar el trabajo”— es fundamental que dominemos las bases y fundamentos del diseño de software. En paralelo, vivimos una época de gran accesibilidad al desarrollo frontend, lo cual es algo positivo. Cada vez más personas ingresan al mundo del código gracias a bootcamps, cursos acelerados y plataformas accesibles. Pero esa misma accesibilidad también tiene un efecto colateral: muchas veces se aprende primero a usar un framework sin comprender las bases que sostienen un software bien diseñado. Y eso genera código que funciona... pero es difícil de mantener, escalar o p…  ( 8 min )

I’ve been working remotely for a while now, and one thing I didn’t expect was how much decision fatigue and miscommunication can mess with your momentum. Coding from home sounds ideal until you realize you’re spending half your time figuring out what the priorities are or waiting on a message that could’ve been a two-minute conversation. So I started experimenting with how I work. Here’s what helped me stay sane and productive as a developer working from home. Clear priorities save hours This structure cuts down on multitasking and gives you a reason to stop over-polishing features that already work. Say more in fewer messages It’s amazing how much faster decisions happen when people understand your intent the first time. Tools don’t solve communication We actually explored some structured approaches to decision-making and planning. One that stood out was Leadership Support. It’s geared more toward alignment and strategy than dev-specific work, but it helped our team communicate better about direction without micromanagement. Takeaway Structure your work Keep your messages clear Choose tools with intention …and most importantly, don’t wait for someone else to fix the mess.  ( 6 min )

As the global surgical robotics market reaches £11 billion and continues its meteoric rise, we stand at the threshold of healthcare's most profound transformation since the discovery of antibiotics. The operating theatre has always been medicine's most hallowed ground, where life and death decisions unfold in moments measured by heartbeats. Today, that sacred space is undergoing its most radical transformation in centuries, as artificia…  ( 25 min )

The Technical Experiment As developers, we often debate AI's impact on our profession in abstract terms. Will GitHub Copilot replace us? Is ChatGPT making juniors obsolete? Instead of another technical analysis, I tried something different: I used AI to write speculative fiction about our augmented future. The result? "The Shadow of Superintelligence: Liberation or a Velvet Cage?" A story that explores Meta's vision of "personal superintelligence" through the eyes of Sarah, a marketer whose AR glasses give her superhuman abilities while her non-augmented colleagues mysteriously vanish.

If you’ve dipped your toes into web development—frontend or backend—there’s a high chance you’ve come across localhost:3000. It’s more than just a port number. It’s the go-to space where development begins, debug logs unfold, and early-stage applications first breathe life. In this blog, we’ll explore why localhost:3000 became a standard, the tools that rely on it, how to troubleshoot it, and how to access it remotely when you're not on the same network. When developers run a local server, it typically listens to requests made to IP address 127.0.0.1, which maps to localhost—your computer. The number 3000 designates the port on which that server accepts connections. So when you visit http://localhost:3000, your browser is reaching out to a web application running on your machine, through p…  ( 8 min )

Unlocking the Power of Edge AI: A New Era for Mobile Applications In today's fast-paced digital world, mobile applications are the lifeblood of our daily interactions, connecting us to everything from social networks to smart homes. Users demand lightning-fast performance, seamless experiences, and, perhaps most critically, ironclad privacy. Meeting these expectations has traditionally relied heavily on cloud computing, where data travels to distant servers for processing before returning to your device. However, this centralized approach often introduces latency, bandwidth strain, and significant privacy concerns. Enter Edge AI. This groundbreaking paradigm shifts artificial intelligence processing from the distant cloud to the "edge" of the network – meaning directly on your mobile dev…  ( 10 min )

As developers, we often gravitate towards the cutting edge: building sleek, high-performance applications leveraging the latest frameworks, cloud services, and device capabilities. Our canvases are vibrant OLED screens, our tools are powerful SDKs, and our users are typically equipped with gigabytes of RAM and blazing-fast 5G. But what if your target user demographic primarily relies on a device with a monochrome screen, a T9 keypad, and connectivity akin to dial-up? This isn't a hypothetical. For millions globally, particularly in emerging markets, the humble feature phone remains the primary gateway to digital services. And for food delivery app development companies aiming for truly universal reach, mastering this domain is not just a business opportunity, but a fascinating engineering …  ( 9 min )

Hey developers! 👋 So I was grabbing coffee yesterday (my 4th cup, don't judge) and scrolling through tech Twitter when I realized something - everyone's talking about the "next big thing" but half of it is just recycled hype from 2019. As someone who's been building stuff on the web since jQuery was considered modern (ouch, I know), I wanted to share the trends I'm actually seeing in real projects, not just conference slides. These aren't just buzzwords - they're things that are genuinely changing how I write code and ship products. Look, I was skeptical about AI coding tools for the longest time. Felt like cheating, you know? But after using GitHub Copilot for six months, I'm not going back to writing boilerplate from scratch like some kind of masochist. Here's what actually happened wh…  ( 9 min )

3D print accuracy can go sideways thanks to unsupported overhangs, messy support interfaces, elephant’s foot bulge and wonky bed leveling – making your models look more blob than beauty. Throw in part shrinkage, sad horizontal bores, skin-thin walls and razor-sharp internal angles, and you’ve got a recipe for dimensional disaster. The fixes? Dial in support patterns, tweak first-layer squish, calibrate your bed leveling, adjust temps to tame shrinkage, beef up bore diameters, thicken those walls and fillet sharp corners.

Most engineers don’t struggle because they can’t code. They struggle because someone misunderstood the client—and now everyone’s sprint is on fire. I’m not a developer. I’m a marketer who works closely with product teams building software for real clients. And over the years, I’ve seen one pattern stand out above all: the best software teams don’t just build clean code—they communicate clearly across teams and with clients. This post is adapted from a conversation with one of the tech leads in my company. It isn’t about email etiquette or vague "soft skills." It’s a breakdown of how experienced dev teams handle misaligned expectations, cross-time-zone clients, and shifting requirements—and still manage to keep trust intact.

A few years ago, I was working with a mid-sized e-commerce brand that prided itself on sleek design and user experience. Their website looked flawless on the surface-modern, fast, mobile-friendly. But after one complaint from a visually impaired customer about being unable to navigate the checkout process, everything shifted. They had never even considered accessibility. I’ve been there-on the other side of a user report, scrambling to understand WCAG (Web Content Accessibility Guidelines), trying to comb through code, running manual checks, and realizing just how many barriers exist for millions of users. It’s humbling, even a little embarrassing. But it’s also where the real learning begins. If you're here reading this, you probably know that WCAG compliance isn't just about ticking boxe…  ( 8 min )

Introduction Significant change is taking place in the rapidly evolving field of artificial intelligence, sparking contentious debates on sites like Reddit and Twitter. It appears that the term “vibe coding”, which refers to a relaxed, frequently unstructured method of using AI agents to generate code, is coming to an end. A usage-based, cost-conscious model is quickly replacing what began as an “all-you-can-eat” buffet for developers and aspiring programmers. This shift represents a fundamental reassessment of how AI should support the software development ecosystem, not merely a change in price. With a valuation of $9.9 billion and a reputation as a “poster child” for AI startups, companies such as Cursor quickly rose to prominence and are now among the fastest-growing AI startups.

When I first started writing about tech, Dev.to felt like the right place to be. It was welcoming, developer-friendly, and had a vibrant community. For a long time, it gave me everything I needed to begin: a platform to share, to learn, and to be seen. But over time, as I started thinking more seriously about what I’m building—not just as a developer, but as a creator—I realized I needed something more. Something that felt like home, not just a guest room in someone else’s house. That’s when I started exploring Hashnode. And I’m moving. Here’s why. It Finally Feels Like My Own Website Dev.to is a great community blog, but it never truly felt like mine.

Todays article will be a bit different as it will not be purely technical but rather motivational one. I was inspired by it after seeing a following meme on X. It will be about my thoughts on Open Source after doing it for a few years now and how we can all benefit from it. Enjoy! The problem is that we all use Open Source in one way or another but we usually do not give enough credit to people who are maintaining it. We use OS tools either directly - by installing an UI library in our web development project to accelerate development of our new website - or as a dependency for other projects - in this case, we usually are not even aware what packages we are using (good luck scanning full lock.json file :D) In some cases, maintainers are not getting anything for their work apart from ba…  ( 7 min )

As developers, we often get caught up in complex technical challenges while overlooking simpler problems that could benefit from elegant solutions. That's exactly what happened when I discovered the Coast FIRE concept and realized there wasn't a straightforward calculator available online. Coast FIRE is a financial strategy where you save aggressively early in your career until you reach a target amount that will grow (through compound interest) to fund your retirement at a traditional age. Once you hit this "coast number," you can stop saving for retirement and focus on covering current expenses. The math is straightforward, but doing the calculations manually is tedious and error-prone. Most FIRE calculators focus on traditional early retirement scenarios.

One thing that hits you fast when you're building anything beyond to-do apps is this: testing matters. That “everything works on my machine” feeling? Doesn’t mean a thing in production. But here's the thing... testing real dependencies in every test? That’s a pain. Slow tests. External services failing. APIs rate-limiting you. And now your tests are flaky, annoying, and worst of all, unreliable. That’s where mocks come in like the chill friend that helps you focus on your actual code without worrying about the rest of the world blowing up. Let’s paint the scene.

Yesterday I was polishing a Dev.to draft when I spotted something truly bizarre in my Markdown: text The “Filter” Nobody Told Me About What I saw: A raw tag instead of a footnote link. What’s actually happening: A Markdown–HTML filter is supposed to replace these with tidy [1] footnotes… but mine slipped through before that step ran. How I Uncovered It Step 2: Hit “Preview” and spotted the odd :contentReference[…] tag in the live render. Step 3: Traced it to the AI’s citation system—basically a “belt-and-suspenders” audit tool that never meant to show end readers this raw syntax. Why You Should Care Hidden metadata risks. If left unfiltered, you might accidentally expose internal tooling details—or worse, break your own Markdown. Conspiracy fuel? It’s tempting to say “they” are spying on your clipboard. But the real culprit is just a busted filter. TL;DR It exists for audit purposes and should have been auto-removed. If you see it too, add a quick find-and-replace, or fix your rendering pipeline!  ( 6 min )

Currently, if you want to vibe code on your phone, one solution is to use something like VibeTunnel to connect to a terminal-based tool like ClaudeCode or similar. However, typing on a phone is inconvenient, and viewing diffs is not very user-friendly either. I’ve developed a Vibe Coding Telegram bot that allows seamless interaction with ClaudeCode directly within Telegram. I’ve implemented numerous optimizations—such as diff display, permission control, and more—to make using ClaudeCode in Telegram extremely convenient. I think these two features significantly improve the mobile experience: The bot currently supports Telegram’s polling mode, so you can easily create and run your own bot locally on your computer, without needing a public IP or cloud server. For now, you can only deploy and experience the bot on your own. In the future, I plan to develop a virtual machine feature and provide a public bot for everyone to use. chatcode  ( 5 min )

Let me tell you something about NEAR that nobody’s really talking about—not the hype, not the usual "fast and scalable" spiel, but the quiet, almost unfair advantages it’s stacking up while everyone’s distracted by the same old blockchain debates. I’ve been building in this space long enough to see patterns—chains rise, chains fall, and most of them just copy each other with minor tweaks. But NEAR? NEAR is playing a different game entirely. It’s not trying to be Ethereum 2.0 or Solana’s cheaper cousin. It’s doing something… sneakier. And if you’re not paying attention, you’ll wake up one day and realize it’s been ahead the whole time. The Thing Nobody Gets About NEAR (Yet) Most comparisons talk about speed, sharding, or gas fees. Boring. Let’s talk about what actually matters: how NE…  ( 6 min )

So you can write clean code, debug like a detective, and your pull requests are rarely rejected. Cool. But why is that guy from the team next door—who honestly writes messier code than you—suddenly leading the new microservices initiative? Welcome to the brutal reality of tech careers: coding skills get you hired, but they won't get you promoted past a certain point. I've been in tech for over a decade, and I've watched brilliant developers get stuck in senior roles while their less technically gifted colleagues climb the ladder. The difference?

前言 有过 GIS 相关开发工作的朋友都知道，GDAL 是 GIS 图形处理最强大的工具，对于 native 客户端和服务端的开发者来说非常友好，提供了适用于多种 CPU 和操作系统的可执行文件和 lib 文件，只要开发者使用的不是小众平台，都能轻松方便地获取。但对于 GDAL 来讲， Web 就是一个小众平台，并没有提供这个平台的任何支持。所以一般地， WebGIS 软件都会将 GDAL 相关服务部署到服务端，客户端通过 HTTP 请求的方式调用。这个方案有一些不足： 通过网络请求调用增加了应用的响应时间，无法实现实时应用 浪费客户端的算力，增加了服务端成本 所以 WebGIS 用到 GDAL 相关的功能时，总是给用户缓慢、卡顿的感觉。 使用 emscripten + WebAssembly 让 GDAL 应用与 web 应用成为可能：GDAL 是一个 C/C++ 项目，emscripten 是一个用于 WebAssembly 的 C/C++ 编译工具，或许能够使用 emscripten 将 GDAL 编译成 JavaScript 可以调用的形式，从而将这个工具移植到 WebGIS 应用中。 对于习惯于编写 JavaScript 的前端开发者来说，如何开始使用 emscripten 就是一个不小的问题。和大多数开源项目一样，emscripten 也是从源码编译开始。这里不大篇幅赘述安装过程，详细请查看 emsdk 文档。如果安装总是不成功，或者懒得安装，也可以使用 emsdk 的 Docker 镜像。 安装好并验证成功之后，就可以开始尝试使用 emscripten 进行编译了。这里举一个简单的例子： // hello_world.c #include int main() { printf("hello, world!\n"); …  ( 6 min )

🧩 Introduction When we talk about Kubernetes security, most developers think of Role-Based Access Control (RBAC) or Network Policies. But before these higher-level controls come into play, there's a foundational layer that silently ensures every component in the cluster is speaking to a trusted source — mutual TLS (mTLS). In a self-managed Kubernetes cluster, unlike cloud-managed solutions like EKS or GKE, you're responsible for configuring, maintaining, and rotating these certificates. Understanding how mTLS works—and knowing where each certificate lives—gives you deeper visibility into the cluster's internal trust system and can help you troubleshoot or harden your deployment. This post will walk you through: What mTLS means in the Kubernetes control plane Which components use certifi…  ( 8 min )

The application may work based on different databases. Databases use similar SQL syntax, but they offer different implementations. As a result, SQL statements need to be modified, only manually. This involves a huge amount of work and becomes error-prone. Completely automated modifications are nearly impossible. After all, different databases probably offer different functionalities. But an examination shows that most obstacles result from the different syntax of SQL functions. The date and string-related functions, in particular, do not have an industry standard. Different database products have different implementations. To transform string "2020-02-05" to date data, for example, they offer different syntax.

STEM — science, technology, engineering, and math — is changing the world we live in. From building apps and curing diseases to solving climate issues and sending rockets into space, STEM is where the future is being shaped. But here’s the thing: women are still hugely underrepresented in these fields. So, what’s holding us back? And more importantly, what can we do about it? Let’s Start with the Facts In areas like AI, cybersecurity, and system design, the number of women is even lower — sometimes under 15%. Many girls lose interest in STEM subjects by the time they reach high school, often because they don’t see enough role models who look like them or because they’re told — subtly or directly — that it’s “not for them.” This gender gap isn't just a diversity problem — it's a missed oppo…  ( 7 min )

Hey everyone, Rhythm Saha here! I'm the founder of NovexiQ, and as a fullstack web developer, I'm usually deep-diving into the MERN stack and Next.js. But today, I want to pull back from the super advanced stuff for a bit. Let's talk about two fundamental React Hooks that are absolutely essential for *any* aspiring developer, no matter where you are on your journey: useState and useEffect. Honestly, when I first started building components, figuring out when to use useState versus useEffect felt like a real puzzle. It was a common struggle, and I totally get it if you're feeling that way too! But trust me, once you grasp their core purposes, they become incredibly powerful tools in your React arsenal. This post is all about making their differences super clear and showing you how to really…  ( 11 min )

Artificial Intelligence (AI) has become a game-changer for developers, transforming how we code, debug, and deliver projects. AI tools are not just fancy add-ons—they’re essential partners that boost productivity, creativity, and problem-solving. Whether you’re a solo coder or part of a large team, here’s how AI is empowering programmers today. AI-powered coding assistants like GitHub Copilot, Tabnine, or even Grok (yep, that’s me!) are revolutionizing code creation: Code Suggestions: AI generates boilerplate code, function stubs, or entire algorithms based on context. For example, type “create a REST API endpoint” and get a working snippet in seconds. Autocompletion: AI predicts the next line of code, saving keystrokes and mental energy. It’s like having a pair-programming buddy who kno…  ( 8 min )

Meaning Domain Control Validation (DCV) is a process used by Certificate Authorities (CAs) to verify that the applicant for an SSL/TLS certificate is authorized to use the domain for which the certificate is requested. In essence, it's a way for CAs to confirm you own or control the domain before issuing a certificate. This ensures that the certificate, and the secure connection it enables, are issued to the rightful owner of the domain. Benefits Blocks Unauthorized Certificate Issuance It is one of the biggest threats in cybersecurity situations that might involve attackers seeking and acquiring an SSL/TLS certificate corresponding to a domain they do not own. Once a cybercriminal acquires and becomes a trusted level with a certificate associated with a domain, a convincing phishing websi…  ( 6 min )

Reactive Programming with RxJS: A Deep Dive Introduction Reactive Programming (RP) is a declarative programming paradigm focused on data streams and the propagation of change. Think of it as an asynchronous dataflow where changes are automatically propagated through the system. Imagine a spreadsheet: when you change a cell's value, all other cells that depend on it automatically update. Reactive Programming aims to achieve this dynamism and responsiveness in software development. RxJS (Reactive Extensions for JavaScript) is a library that brings the principles of Reactive Programming to JavaScript. It provides a powerful set of tools for working with asynchronous data streams, events, and interactions, making it a cornerstone for modern web and application development. By using RxJS, dev…  ( 8 min )

I had a need to mirror my Android screen to my computer, and I found a really convenient way to do it — using Wireless Display, a built-in feature included for free in Windows. This method allows you to share your mobile screen with your PC without using any third-party apps. Miracast is a wireless technology that allows you to transmit both video and audio from one device to another via Wi-Fi Direct — no HDMI cables or additional apps required. Often referred to as “wireless HDMI”, Miracast supports high-resolution streaming, including 1080p and even 4K, depending on your hardware capabilities. 1. 🟠 Wi-Fi Direct (P2P / Ad-hoc) No router or access point (AP) is required Temporarily disconnects the phone from its current Wi-Fi This is the classic Miracast mode (defined by the Wi-Fi Allian…  ( 10 min )

Cuzzy, let's be real - every time people start shouting about AGI like it's some second coming, I just smile. You'd think the way they talk, there's one massive god-tier AI about to descend from the cloud and start handing out verdicts, replacing jobs, coding startups from scratch, reading your thoughts before your IDE even boots up. But step out of the Twitter thinkpieces, unplug from the hype, and look at what's actually happening in the trenches - dev trenches, real workflows, everyday chaos. What you'll see isn't some singular AI deity. It's a bloody pantheon. I'm talking gods. Plural. Each with its own flavour, its own superpower, its own weakness.

So you're building something cool and need to choose between AWS Lambda and Cloudflare Workers? Been there, done that, got the t-shirt (and probably a few sleepless nights debugging cold starts). Let me save you some time and share what I've learned from wrestling with both platforms in production. Before we dive into the nitty-gritty, let's talk about what makes these platforms fundamentally different. It's not just about branding or pricing—we're looking at two completely different approaches to running code in the cloud. AWS Lambda is like having a really smart building manager. When someone needs an apartment (your function), they either give you an existing one that's ready to go, or they go build a new one from scratch. This can take anywhere from milliseconds to several seconds, dep…  ( 8 min )

API security testing is the process of evaluating the defenses of APIs to ensure they are resistant to vulnerabilities and unauthorized access. It is also now a major part of the software development lifecycle (SDLC), where developers even test the API before they are deployed. Businesses hire cybersecurity companies to perform API security testing to find vulnerabilities or weak points through which attackers can infiltrate the system. As a result, you can know where the security flaws lie and take the necessary steps to fix them. Importance of API Security Testing for Companies The fast growth of digital changes and the widespread use of APIs have led to a new era where systems and services are more connected. However, relying more on APIs also brings new security challenges. Integratio…  ( 7 min )

Welcome to Day 24! Today I explored how to choose between using loops or iterators in Rust and why iterators are preferred in most idiomatic code. I also learned about zero-cost abstractions, an important concept in systems programming that Rust excels at. At first glance, using a traditional for loop might feel more intuitive, especially if you’re coming from C-style or JavaScript programming. But Rust encourages using iterators for a cleaner and more expressive approach. Focus on what needs to be done, not how. Cleaner and more declarative. Less boilerplate. Easier to reason about complex chains of operations. Iterators abstract away common loop mechanics and let you concentrate on the filtering, mapping, and reducing logic. Think of iterators as the Rusty version of chaining methods in …  ( 6 min )

If you think Agile is all about stand-ups and sprints… you're only scratching the surface. Agile methodology that’s laser-focused on writing better code, faster — and it's not Scrum. It's called Extreme Programming (XP) — and it's a game-changer for developers who care about clean code, tight feedback loops, and high-quality software delivery. Let’s dive deep into how XP can upgrade your development mindset — and help you ship better software without burning out. XP is an Agile framework that focuses on improving software quality and responsiveness through frequent releases in short development cycles, which improves productivity and introduces checkpoints at which new customer requirements can be adopted. It was created by Kent Beck in the late '90s, and while many developers know the na…  ( 7 min )

As a long-time Ubuntu user—from 18.04 to 24.04—I’ve always appreciated the system’s stability. However, when it comes to package management, things can become a bit frustrating. For non-repo apps, I often fall back on Flatpak. It has a solid ecosystem, but let’s be honest: it’s heavy, slow to launch, and not exactly snappy for lightweight tools. So recently, I’ve been on the lookout for alternatives. When deepin 25 launched, I noticed they introduced a new package manager called Linyaps. Having been a deepin 15 user in the past, I decided to give it a shot. Installation: Surprisingly Simple Linyaps Website echo "deb [trusted=yes] https://ci.deepin.com/repo/obs/linglong:/CI:/release/xUbuntu_24.04/ ./" | sudo tee /etc/apt/sources.list.d/linglong.list After installation, I tried a few basic apps. The command-line tool ll-cli works similarly to apt, perfect for terminal-savvy users. Linyaps App Store It can also download the app store client. Uninstalling or updating apps can only be done through this client, though. That said, it only seems to have a Chinese interface so far – I couldn’t find an option to switch to English. Maybe that’s still in the works; hope they iron that out soon. Real-World Experience Even after just a few hours of use, Linyaps runs surprisingly smoothly on Ubuntu 24.04. It feels faster than Flatpak and hasn’t shown any compatibility issues so far. Sure, it doesn’t have the massive ecosystem Snap/Flatpak has yet, but for daily use? Definitely worth trying.

I've recently started writing about how I'm building PocketBase.Net in the Building PocketBase.Net Step by Step series. However, I haven't had the opportunity to go over what was already in place. In particular, having a robust testing suite with both unit and integration tests was a very important point for me, as the library could potentially be used by others to manage their data, which is often the most critical part of applications. In this article, I will explain how I set up a working testing environment for my integration tests, using a dockerized PocketBase instance with TestContainers. As software engineers, we are (I hope) used to testing our code.

Your company just ordered a batch of new laptops, but when they arrive, some of them are different models from those expected. IT updates the inventory, but the records are inconsistent. Some assets are listed by brand name, others by serial number, and a few have no details at all. When audit time comes, everything turns into a scramble. This situation is more common than most businesses realize. With so many devices, applications, and licenses to manage, things can get messy fast if there’s no clear structure in place. Asset models help solve this problem by standardizing how assets are recorded and managed, based on details like make, model, and specifications.

Word Embeddings An assignment of words to numbers is called a word embedding. Consider an example, suppose we have a 2D plane and at multiple coordinates we have some labels like apple, banana, mango are near to each others coordinates, similarly carrot, radish and potato are near each other, and laptop, mobile, TV are far from the vegetables coordinate and fruit coordinate also. Now if we have to place "orange" then think around which coordinates it should be place? It should be placed with fruits, near banana, mango and apple. Words that are similar should correspond to points that are close by. Words that are different should correspond to points that are far away. There is something more to these word embeddings, and it is that they don’t only capture word similarity, but they also c…  ( 8 min )

A backlink is a link created when one website links to another. Backlinks are important for both helping people discover your website and improving your ranking on search engines like Google. Think of backlinks as trust signals or votes of confidence from other websites. The more high-quality backlinks your website has, the more likely it is to rank higher in search results. For example, imagine you run an online bookstore. If a popular blog about reading links to one of your pages, that link becomes a backlink for your site. It not only brings more readers to your store but also tells search engines that your website is credible and valuable. Learn how to check and analyze backlinks, which backlinks will be worth your time, and where to get them.  ( 5 min )

I originally posted this post on my blog. Pierre started coding back in the 60s and still maintains a 30-year-old codebase. Thanks to the magic of the Internet, and to one of my posts going viral, I've exchanged a couple of emails with Pierre. I don't know him in real life, just on the Internet. His story has captivated me from the beginning. I know only about a few industry veterans, and even fewer who are still actively coding. Since the 60s, Pierre has gone through every boom and hype in this industry. He witnessed the Y2K panic, the birth of Java, the rise of Agile, and probably more that I don't remember now. In one of our emails, I asked Pierre about his take on AI. Today, we only see headlines of CEOs claiming AI generates most of their code, along with headlines saying coders are doomed. But, here's what Pierre, with his wealth of experience, told me about AI (slightly edited for brevity): I'm skeptical about AI. I just don't see automatically generating code from typical imprecise specifications...Apparently we've run out of Internet on which to train AI. It is now feeding on its own hallucinations, like mad cows eating their own prion-riddled offal, or the inbred Hapsburg dynasty. If Pierre, who has seen quite a lot, is skeptical, we shouldn't be worried. I'm not. Pierre reminded me of that joke/meme that we're still safe because AI needs unambiguous and well-written requirements. As long as clients who don't know what they want exist, we're still in business. I don't think AI is taking our jobs anytime soon. Sure, we have to adapt. AI is changing the landscape. For sure, coding in 2034 will look different. Coding today doesn't look the same as coding back in the 70s. We can't ignore AI. AI is like using calculators in math classes. They make us faster, sure, but they can't do the thinking for us.

Mastering the Viewport: An Intro to CSS Media Queries When we create a website, we want it to look good on every device, from a large desktop monitor to a small smartphone screen. This is the core principle of responsive web design, and the key tool for achieving it is the CSS media query. A media query allows us to apply specific styles only when certain conditions are met, such as the screen width. This means we can serve a different, optimized layout to a user on a mobile device without building a completely separate website. It's how a website can "respond" to its environment. Let's look at a simple example. We'll start with a basic layout that works on desktop, and then use a media query to change it for mobile. Our Default (Desktop) Layout /* Styles for screens larger than 768px (the default) */ .container { display: flex; justify-content: space-between; padding: 20px; background-color: #f0f0f0; } .box { width: 30%; padding: 20px; background-color: #007bff; color: white; text-align: center; border-radius: 8px; } This CSS creates a horizontal row of three boxes, perfect for a desktop screen. The Mobile View: Using a Media Query @media (max-width: 768px) { .container { flex-direction: column; /* Stack the boxes vertically */ align-items: center; /* Center the stacked boxes */ } .box { width: 90%; /* Make the boxes wider to fill the screen */ margin-bottom: 15px; /* Add some space between them */ } } This code tells the browser: "When the screen is 768 pixels wide or less, apply these new styles." The flex-direction: column property is the magic that changes our layout from a row to a stack, and we adjust the box width and margin to make it look great on a phone. By using media queries, you can ensure your web applications are not only functional but also provide a great user experience, no matter how a user is viewing them. It's a fundamental step in building modern, accessible websites.  ( 6 min )

What is JavaScript? JavaScript is a high-level,dynamic and interpreted programming language used to make websites interactive. we can use it to control anything like data validation, button functionality,animation updates and more. Every value in JavaScript has a specific type. This type determines what operations can be performed on the value and how it is stored. There are 8 basic data types in JavaScript String Number Bigint Boolean Undefined Null Symbol Object In a programming language, variables are used to store data values. JavaScript uses the keywords var,let and const to declare variables. Only use var if you MUST support old browsers. use let when reassignment is needed Always use const if the value should not be changed Arithmetic Operators Assignment Operators Comparison Operators String Operators Logical Operators Bitwise Operators Ternary Operators Type Operators let str1 = "Hello"; let str2 = "World"; let result = str1 + str2; console.log(result);  ( 5 min )

Problem You need to validate incoming JSON data in POST requests to ensure required fields exist, have correct types, and meet specific criteria before processing. const express = require('express'); const { body, validationResult } = require('express-validator'); const app = express(); app.use(express.json()); // Validation middleware const validateUser = [ body('email') .isEmail() .withMessage('Must be a valid email') .normalizeEmail(), body('password') .isLength({ min: 6 }) .withMessage('Password must be at least 6 characters'), body('age') .isInt({ min: 18, max: 100 }) .withMessage('Age must be between 18 and 100') ]; // Route with validation app.post('/api/users', validateUser, (req, res) => { // Check for validation errors const errors = validationResult(req); if (!errors.isEmpty()) { return res.status(400).json({ success: false, errors: errors.array() }); } // Process valid data const { email, password, age } = req.body; res.json({ success: true, message: 'User created successfully', user: { email, age } }); }); app.listen(3000, () => { console.log('Server running on port 3000'); }); Install express-validator: npm install express-validator express-validator provides middleware functions that validate request data. Each body() call validates a specific field with built-in validators like isEmail(), isLength(), and isInt(). validationResult(req) collects all validation errors. If errors exist, return a 400 status with error details. The validation runs before your route handler, so you always receive clean, validated data when validation passes.  ( 5 min )

I've been developing software for almost 3 decades, and I've lost count of how many brilliant ideas vanished between conception and keyboard. You know the feeling – that perfect solution hits you in the shower, during a run, or right as you're falling asleep. Last month, I started dogfooding my own tool – VoiceCommit – to create GitHub issues directly from voice. The results surprised me: I've created 20+ actionable GitHub issues from ideas that would have 100% disappeared within minutes. Here's the truth: It's not about saving time. It's about saving ideas. The Old Reality: Have idea while walking → "I'll remember this" → Open laptop 2 hours later → What was that idea again? Success rate: Maybe 1 in 10 ideas survived The New Reality: Have idea → Pull out phone → 30-second voice note → Gi…  ( 8 min )

In this article we will show how to develop a Dynamic Array in C and also talk about the advantages and disadvantages of each strategy of memory initialization for arrays. Basic knowledge of programming (logic, etc); C syntax, allocating variables; Memory management in C: pointers, malloc, calloc, realloc, free; An array that can grow or shrink in size during runtime. Unlike static arrays, which have a fixed size, dynamic arrays automatically resize as elements are added or removed. Is it a good idea to start an array with a small size and then realloc it? It depends. If the current memory block can't be extended contiguously, realloc will allocate a new block and copy all n items. Which results in O(n) operation and can cause an overhead.

I'm now writing something about my feeling of posting article on DEV. I have read many of this before, it inspired me to share about my feelings to us. As a beginner, I know that sometimes I don't have many ideas to write about. When I read others word, I can always learn a lot. They tell you the knowledge of programming, but after reading, it is also difficult for me to write something. I just shared one of my projects, it's a simple algorithm. I knew that I don't have many projects to share, maybe sharing some of my feeling, but most of the time I don't know how to write it in words. Some of the feeling can't tell others through words, maybe many of us feel the same, just lack of communication. I just want to write perfect articles, for me, and for everyone. I have been programing for some years, but as a student, I don't have many times to do this. Although I have continue doing this for about 6 years, I'm just a beginner. Programming is not strange to me, but my first article was written in last month. It was my first time to write about my work. I just want to record myself. Although it hasn't been shown to many of others, it is also important to me. It my first post, the first time I try to write something. I'm not perfect in writing articles, but what I need to do is, thinking more, and writing more. Writing needs time and effort, when I write this, I need to think about how to organize my word, how to swich the programming language to natural language. Not just copying and pasting the code, nobody likes it. I want to talk more, but I'm just lack communication. I want to tell many things. I want to talk about my feeling of programing, even how I started writing my first "hello world". It's a long story, just to share it in the future.  ( 6 min )

Introduction: The White Lie Inside Your Computer Look at your computer's system information. If you have a modern processor, you will likely see a number of "processors" or "threads" that is double the number of actual, physical cores inside your CPU. An 8-core processor might report that it has 16 logical processors. A 12-core chip might appear as a 24-threaded behemoth. This isn't a bug. It's a deliberate and calculated deception—a clever white lie told by the hardware to the operating system. This phenomenon, known generically as Simultaneous Multithreading (SMT) and most famously by Intel's trademark, Hyper-Threading, is one of the most successful performance-enhancing technologies in modern computing. It is a trick designed to solve a fundamental problem of efficiency: the fact that…  ( 13 min )

Users can add GitHub repositories to their collection and then search through them using natural language queries that go far beyond simple keyword matching. 🔗 Repository: My Awesome Boilerplate The project showcases a complete implementation of vector similarity search usin…  ( 6 min )

Introduction: The Paradox of Added Complexity It sounds like a recipe for inefficiency: the instructions your software painstakingly sends to a processor are not the instructions that the processor actually executes. Instead of acting on them directly, a modern Central Processing Unit (CPU) subjects these commands to a complex, energy-intensive process of translation and decomposition. It's as if you gave a builder a detailed blueprint, only for them to redraw it into a completely different set of plans before picking up a single tool. Why would hardware designers introduce this seemingly redundant layer of complexity? Why not build a processor that simply does what it's told, one instruction at a time?

While this implementation uses Python, the architectural patterns and SurrealDB integration strategies apply to any language with SurrealDB SDK support. Standard Retrieval-Augmented Generation (RAG) models are powerful but operate on single shot principle: Retrieve then Generate. This approach often fails when faced with complex multi-faceted queries, providing incomplete answers that lack depth. The core limitation is the absence of a feedback loop. This article introduces the Reflexion RAG Engine, a production-ready system that overcomes these limitations through a multi-cycle, self-correcting architecture powered by SurrealDB. It employs a Multi-LLM strategy for Generation, Evaluation, and Synthesis to iteratively refine answers, ensuring higher accuracy and comprehensiveness. SurrealD…  ( 17 min )

Git Branching Branching is a fundamental concept in Git that allows you to work on new features or fixes independently from the main codebase. Each project starts with a default branch (usually main or master), and you can create as many additional branches as needed. Once your work is ready, you can merge your branch into another using a pull request. Branches help you safely test changes, build features, and fix issues without disrupting the main project. Git Reset vs Revert Both git reset and git revert help you undo changes in your code, but they serve different purposes: git reset moves the pointer of your branch to a previous state and can modify your commit history (best used in local branches). git revert creates a new commit that undoes the changes from a previous commit, pres…  ( 7 min )

Computer science is a huge field, spanning web dev, systems engineering, AI, and more. It’s super easy to dive into high-level stuff like building apps or websites with modern tools and frameworks. But that ease means a lot of people skip the low-level basics. How computers actually work, how code becomes machine instructions, or what’s happening in the hardware. Knowing this stuff, like memory management or how the CPU and OS interact, gives you a deeper edge. You’re not just coding—you understand why things work or break. The industry pushes quick results, and focus on job-ready skills, so the low-level foundations often get ignored. But grasping what we are doing is what makes us a better developer. Your enthusiasm for relearning computer science as a self-taught enthusiast is infectious! Diving deep into the world of computer science is thrilling, but the complexity of how computers work can feel daunting. So, how do we tackle this? How do we unravel the intricate layers of a computer’s inner workings and build a solid understanding from the ground up? But common we are devs; we work with complex systems everyday. Alright, so how are we going to do this? The answer has been right in front of us all along: books. There are countless books we could follow, but I’m going to focus on the one i am reading. "The Elements of Computing Systems" - Noam Nisan and Shimon Schocken. It is a fantastic resource I discovered while browsing the internet. tackling every problem from the ground up in a beautifully clear and engaging way. I’ll soon share updates on my progress with this project, detailing my learnings and celebrating the joy of engineering. Thanks for reading! Note: I am also a beginner, trying to learn. So if you have something for me to learn. Contact Me!  ( 6 min )

Ever glued together socat, raw JSON, and a prayer just to talk to QEMU from Go? I did—until one missing comma killed an overnight CI run. So I bolted a Go backend onto QEMU’s own QAPI generator, and now every VM call is type-safe, fully async, and always in sync with upstream. ➡️ Check out the project on GitHub QEMU already ships a rich JSON interface (QAPI), yet Go developers still end up: Writing raw JSON by hand – easy to mistype, hard to test. Chasing partial wrappers – most cover only “common” commands. Fixing silent schema drift. Fully typed bindings for every command, struct, and enum in qapi-schema.json. Async events & requests via goroutines and channels—no polling loops. Transport helpers for QMP, QGA, serial pipes, TCP, stdio… the lot. Schema-sync guarantee – regenerate on eac…  ( 6 min )

If you've been building with LLMs for a while, you've probably experienced that moment when the model feels like it's more of a hindrance than a help. Worsening quality of answers, constant reminders to start a new chat window, and constraints that continually get forgotten. These are all symptoms of what happens when the models context starts to get too polluted. When building ai agents these problems can be the difference between having a reliable production ready agent and having a system that works great in your local tests but breaks in production. To bridge this gap and have a consistently reliable agentic system, you need to know how to effectively manage context. This is where context engineering comes into play and is essential for reliable agent building at scale. Before we dive …  ( 9 min )

LeetCode 1: Two Sum Problem: Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order. public int[] TwoSum(int[] numbers, int targetSum) { var numberToIndex = new Dictionary(); for (int currentIndex = 0; currentIndex < numbers.Length; currentIndex++) { int currentNumber = numbers[currentIndex]; int requiredNumber = targetSum - currentNumber; if (numberToIndex.ContainsKey(requiredNumber)) { return new int[] { numberToIndex[requiredNumber], currentIndex }; } if (!numberToIndex.ContainsKey(currentNumber)) { numberToIndex[currentNumber] = currentIndex; } } throw new InvalidOperationException("No solution exists for the given input."); } Instead of checking every pair with a nested loop, we can use a dictionary to remember the numbers we’ve seen as we scan the array, storing the value and its index. We loop through each number, and subtract it from the target. If the result exists in the Dictionary, we know we've found our two numbers and can return the indexes of these numbers. But wait how does result = target - currentNumber give us the two numbers? Well, because if we can't find a match we still add the currentNumber to the Dictionary, so we keep a record we've seen that number somewhere in the array. Target is 20; result = 20 - 7 = 13 index of 13 and index of currentNumber and Bingo we have our two numbers. Well, simply because all paths in a code base need to return a result. However, instead of returning [0,0] which is wrong, we throw an exception to show we've handled all paths, but wasn't a valid outcome.  ( 6 min )

In the Go programming language, Goroutines and Channels are essential concepts in concurrent programming. They help solve various problems related to concurrency. This article focuses on select, which serves as a bridge for coordinating multiple channels. select What is select select is a control structure in Go used to choose an executable operation among multiple communication operations. It coordinates read and write operations on multiple channels, enabling non-blocking data transmission, synchronization, and control across several channels. select The select statement in Go provides a mechanism for multiplexing channels. It allows us to wait for and handle messages on multiple channels. Compared to simply using a for loop to iterate over channels, select is a more effic…  ( 10 min )

Java Records, finalized in Java 17, provide a concise way to create immutable data carriers. But what happens when your clean Record needs to validate its data? Suddenly, that elegant one-liner becomes a validation challenge. Let me show you three approaches to Record validation I've encountered in production code, and why I ended up building a new solution. Consider this simple user registration scenario: public record User(String name, String email, int age) {} Clean, right? But in production, you need validation: Name: 2-50 characters, not null or empty Email: valid format, not null Age: 0-120, reasonable range Suddenly, your elegant Record isn't so simple anymore. The most straightforward approach is manual validation in the compact constructor: public record User(String name, String …  ( 8 min )

Apple’s product pages are great examples of clean design, subtle animation, and precise typography. Inspired by this, I set myself a challenge: could I recreate the AirTag landing page and present the process in under ten minutes? The result is a pixel‑perfect build using React (Vite) and Tailwind CSS, documented in an eight‑minute speed‑run video. The official AirTag page opens with the tagline “Lose your knack for losing things” and uses simple sections like: “Ping it. Find it.” “Precision Finding” “Get by with a little help” (apple.com/airtag) These elements make it a great UI challenge—minimal content but high polish. Scaffolding – Bootstrapped a Vite + React + TypeScript project and added Tailwind CSS. Figma – Created a layout in Figma inspired by Apple’s page and exported the assets. The Figma file is included in the repo’s figma folder. Components – Each section (hero, feature cards, CTA) is a separate React component. Tailwind utility classes handle spacing, and typography. Speed‑run video – I recorded the build process and condensed it into a fast-paced video that runs just over eight minutes. 🎬 Watch the 8‑minute build video 💻 Browse the code on GitHub Utility‑first styling speeds things up – Tailwind let me prototype quickly without leaving the markup. Figma is a great source of truth – Having a pixel‑perfect reference meant less guesswork. Feedback is invaluable – I’m eager to hear from other front‑end devs—how would you enhance this? Maybe add animations Improve accessibility Refactor the component structure? Feel free to share feedback in the comments or submit pull requests!  ( 6 min )

RuneScape has been around for over twenty years but the private server community is still growing. In fact it feels more active now than ever before. Private servers or RSPS let players enjoy the game in new ways. Some servers offer faster leveling. Others have custom bosses or completely different content. What used to be small projects with bugs and missing features have become stable games with big player bases. So what is driving this growth One reason is better tools. Developers now have access to more open source server files and better client emulators. Setting up a server used to take weeks. Now it can be done in a day. Some developers have even added their own systems like raids or skill trees from scratch. Another big reason is mobile gaming. More people are playing games on their phones so RSPS owners are starting to think about mobile support. A few servers already run well on Android and more are working toward that. AI tools have helped too. Some RSPS developers use AI to help write quests or fix bugs faster. This saves time and keeps players engaged with fresh content. Promotion is also easier now. There are websites that list and rank servers so players can find active ones quickly. One of the most updated sites is rsps100.com where you can browse top servers by votes or activity. If you are a developer or even just curious about game design RSPS is a great space to explore. You can learn about multiplayer systems economy balancing and player feedback all in a live environment. Private servers are not just copies of the original game anymore. They are creative projects shaped by both nostalgia and modern tools. And they are not slowing down anytime soon.  ( 6 min )

Hey Dev community! We've all been there. You've just finished coding a project you're proud of. The UI is slick, the logic is solid, and it's running perfectly on localhost. Now comes the part that can often be a chore: deployment. Setting up servers, configuring build pipelines, managing SSL certificates... it can be a real momentum killer. For my latest project, Foundry.AI, an AI-powered branding tool built with React, I wanted to find a deployment solution that was as fast and modern as the app itself. I decided to try Tencent Cloud's EdgeOne Pages, and I was genuinely blown away by how incredibly smooth and easy the process was. Today, I want to walk you through how I took my React application from a GitHub repository to a live, globally-accelerated URL in literally under 5 minutes. Th…  ( 7 min )

✅ Built my MVP in a weekend If you’ve been lurking on Hacker News, Dev.to, or Indie Hackers waiting for the “right time” to build your startup… The time is now. In 2026, building a profitable Micro SaaS is easier than ever—and you don’t need VC money, a big dev team, or even to write much code.

Overview In this post, we’re going to talk about what exceptions are and how to handle errors in a Java project using @ControllerAdvice. We’ll go over creating custom exceptions and sending back the right HTTP status codes. By the end, your API will be easier to maintain, more reliable, and give your users clearer error messages. Let’s start with the basics: what’s an exception? Trying to access a file that doesn’t exist. Dividing by zero. Our always friend, NullPointerException. When an exception occurs: Java creates an exception object with details about the error. The regular flow of the application stops. Java tries to find a matching handler to deal with the exception. There are two main types of exceptions: Checked exceptions → Must be either caught or declared (e.g., IOException).…  ( 6 min )

Veo 3 is a powerful video generation model by Google Deepmind, which was originally available through Vertex (Google Cloud). Now available with Google Gemini Pro, it can be used with limited access. The usage is limited to 3 videos per day and also the video that can be generated is 8 seconds. Though the numbers are very small, it can be fun to experiment with it. Here are some of the prompts that I tried with this video generation: For the initial attempt, I went with one of the traditional concepts using a cat and it was good. A kitten playing guitar in a street For the next one, I tried to get a video of screen recording/sharing of a code editor with some Python code. Even though the specifications are mentioned in the prompt, the video that was generated by the model wasn’t very accurate with respect to the specifics. A screenshare video (macOS — Visual Studio Code Editor) of typing a Python code (code for factorial of a number) without any audio It was able to create the title for the video very specific to my description in the prompt but not the video :) The above examples are with the mode of Text-to-Video. Additionally, you can try to create a video with an image input (something like Image-Text-to-Video) with the prompt to the model. This is still limited to the 8-seconds video length restriction. This video generation model can also be accessed via Gemini API on a paid-preview basis (more details on the official documentation page). Try out some of your own prompts and play with the model.

The Temptation You’re building a dashboard and need a profile card for the logged-in user. function Dashboard({ user }) { function ProfileCard() { return ( {user.name} {user.role} Dashboard ); } It works. The UI renders. You move on. 🚀 Every time Dashboard re-renders, whether because user changes or some unrelated state updates, React recreates the ProfileCard function. That one fact breaks React’s reconciliation process and can lead to: State loss inside ProfileCard Extra unmount/mount cycles Wasted DOM operations Reconciliation is how React updates the UI without throwing everything away.

As organizations adopt microservices architecture and Kubernetes for deploying containerized applications, one critical question arises: “How do external users securely access my services running inside the Kubernetes cluster?” By default, Kubernetes provides service types like ClusterIP, NodePort, and LoadBalancer to expose applications. However: ClusterIP only allows internal access. NodePort exposes your app on every node's IP and a static port — not ideal for production. LoadBalancer provisions a cloud provider load balancer — but one per service, which is expensive and harder to manage at scale. Imagine a production app with: A frontend UI service A backend API service An admin dashboard A metrics endpoint If you use LoadBalancer for each, you’ll quickly rack up cloud costs and lose c…  ( 8 min )

Language models have become surprisingly capable at many tasks, from writing code to answering complex questions. But there's a troubling phenomenon lurking beneath their impressive performance: hallucinations. These aren't the mysterious visions of science fiction, but something far more mundane yet equally concerning—AI systems confidently generating information that simply isn't true. At its core, an LLM hallucination occurs when a model generates content that sounds plausible and coherent but is factually incorrect, nonsensical, or completely fabricated. Think of it as the AI equivalent of someone confidently telling you that Napoleon won the Battle of Waterloo or that there are 14 months in a year. The information flows smoothly and convincingly, but it's fundamentally wrong. The phen…  ( 9 min )

Most people understand the basics of what git is. add, commit -m "please work", push. Well, having this for a git workflow makes it feel like a burden more than a tool. Lemme expand your mind a little bit. Imagine your code like a story one you're telling to your future self or another developer joining you. Every commit is a chapter, every branch is a plot thread, and every merge is where storylines converge. When viewed this way, Git transforms from a mundane version control system into a powerful narrative tool that makes your development journey coherent, traceable, and beautiful. A well-crafted commit message is like a good book title it tells you exactly what to expect inside. Instead of cryptic messages like "fix stuff" or "updates," consider commits as documentation of your thought…  ( 8 min )

⚠️ This article was translated by AI. Click here to read the original version in Portuguese. In large-scale system development, the quantity and complexity of microservices can become a formidable enemy. After facing this enemy multiple times, I refined a set of architectural patterns. These patterns are the foundation of an approach I call Gateway-Oriented Architecture (GOA). GOA doesn't propose new components, but rather the disciplined organization of consolidated patterns to achieve maximum productivity and security. Gateway-Oriented Architecture (GOA) aims to simplify microservices development by isolating security and communication complexity into specialized components called Gateways. Instead of having each microservice handle authentication, authorization, routing, and public ex…  ( 7 min )

Among the various search algorithms, Linear Search stands out as the most fundamental. In this article, we will delve into the workings of Linear Search and break down its implementation step by step. Linear Search is a simple search algorithm that examines each element in a list one by one until it finds the desired element or reaches the end of the list. It doesn't need the data to be sorted. Let’s use the array below as an example and say we need to search for the number 63. The algorithm will first check the first element, 80. The index pointer will ask: “Is 80 the number we need?” The algorithm responds: “No, it’s not!” The index pointer moves to the next element, 14. The pointer asks, “Is 14 the number we’re looking for?” The algorithm replies, “No.” It will then move to the nex…  ( 8 min )

This isn't just a nice-to-have anymore—it's table stakes for modern enterprise systems. Zero-downtime architecture is the art and science of designing systems that remain operational during updates, maintenance, and even partial failures. It's about creating resilient systems that can evolve without interrupting the user experience. But let's be…  ( 13 min )

Recently I experimented with Cognito secured AWS API Gateways and came across an annoying problem - how can I test my application end to end without having to log in to Cognito with a Browser? Removing the Cognito Authorizer for testing purposes would be one option, but there are cases where applications make use of the tokens for access control or other mechanisms and changing the application behaviour with regards to tokens just for tests doesn't seem be right. Fortunately, CDK supports custom AWS resources that can be used to create dummy users with all the attributes necessary! First, we define a Lambda that backs our API. For the purposes of this, the Lambda will just return the AWS Region in which it runs. producer/main.go package main import ( "context" "encoding/json" …  ( 7 min )

Lately I’ve been trying to get more consistent with my Linux workflow — not just using it, but actually understanding what’s going on under the hood. While looking for practical, no-fluff resources, I came across this site that really clicked with me. It’s not overwhelming or packed with ads; just clean, focused content. There’s a section called the Linux Library that I’ve bookmarked already. It breaks down commands, concepts, and tools in a way that feels like a cheat sheet you’d actually use. Whether you’re brushing up on your terminal skills or exploring new tools, it’s super handy. What I liked most is that it doesn’t assume you’re a beginner, but also doesn’t throw jargon at you without explanation. It feels like it was written by someone who actually uses Linux daily and gets what’s useful in real-life situations.  ( 5 min )

In recent months, the term vibe coding has gained traction — generating code with the help of AI, iterating quickly until you get something that works. Does it work? Yes, especially for problems that are widely documented on the internet. But like any powerful tool, it must be used consciously — especially in a corporate environment, where the challenges are very different from GitHub tutorials. This article walks you through a debugging process you can apply to ensure that the code generated (by you, AI, or colleagues) actually works. It also covers where AI shines and where it tends to fail. 1. Where AI Works Well — and Where It Fails AI is great at solving problems that have already been solved and are widely documented.

The field of software engineering is undergoing a profound transformation, driven by the rise of Artificial Intelligence (AI), Machine Learning (ML), and Large Language Models (LLMs). What was once a discipline grounded in rigid processes and strict team roles is rapidly evolving into a more dynamic, intelligent, and automated ecosystem. From Traditional Teams to Intelligent Orchestration Enter AI and LLMs. Today, with the advancement of technologies like Model Coordination Protocols (MCP) and AI-driven development assistants, many of these roles are becoming partially or fully automatable. We’re no longer just writing code — we’re architecting systems that write, test, review, and even debug themselves. The MCP Engineer: A New Role in the AI Era Here’s how the process unfolds in this new paradigm: The engineer feeds high-level product requirements into the system. An LLM generates UI/UX mockups based on user personas and product goals. Another model creates a development plan, breaking the work into frontend, backend, and integration tasks. AI agents write code, generate API specs, and build responsive UIs. Test suites are auto-generated and executed, including edge cases. Documentation is produced as the system understands what it built. The product is deployed via automated CI/CD, and monitored using AI-powered observability tools. Throughout this process, the MCP engineer supervises the automation — identifying failures, debugging AI misinterpretations, and refining prompts or training data. Why This Matters It’s not about replacing creativity with code generation — it’s about scaling creativity across the stack. The Future Is Collaborative Intelligence Engineering, in its modern form, is becoming less about typing lines of code and more about orchestrating intelligent subsystems — like a maestro guiding a symphony where each instrument is powered by AI.  ( 6 min )

Tagasaurus is a privacy-first media-manager that lives entirely on your desktop. Drop photos, videos, GIFs, PDFs, or audio files into the app and Tagasaurus builds a fully local library you can search like magic. Type a natural-language description ('sunset over the vacation 2019', 'college picnic 2012') or let the camera roll: Tagasaurus can find every shot of your old friend Jack by comparing face embeddings even if you never wrote a single tag. Because everything runs offline, none of your memories ever leave your machine. It can handle storing audio, pdfs, gifs and video. https://github.com/mantzaris/Tagasaurus/ Under the hood the app is a tight Electron JS bundle with a modern Svelte 5 + Routify frontend. The renderer is written in TypeScript with runes-based reactivity and Tailwind-style utility classes, while the main process handles heavy lifting in Node. Media ingest pipelines lean on fluent-ffmpeg (pointed at statically bundled ffmpeg/ffprobe binaries) to extract thumbnails, duration metadata, and frames for face detection. Faces are embedded with an ArcFace ONNX model; text search uses a lightweight sentence-embedding model—both executed through onnxruntime for fast, CPU-friendly inference. Vectors, file hashes, and canonical paths land in a libSQL (SQLite) database, giving you ACID guarantees and blistering full-text + nearest-neighbour queries without shipping a server.

Meilisearch is a really powerful search engine; it’s fast, open-source, and easy to set up. But if you don’t configure it properly, especially the indexing and attributes, it can start to feel slow. Let’s say you set up an index with a few thousand records and start running searches. At first, things feel snappy — queries respond in under 20ms, which is very fast. But then you notice that some searches — especially those with 3 or more keywords — are suddenly taking above 300ms or more, even on a local instance. Making just a few small tweaks to how you set up your indexes and attributes can significantly improve speed and overall performance. Have you ever felt like your Meilisearch results are a bit slow? Maybe you’ve had to wait longer than expected for a simple search to load. In many …  ( 10 min )

The first real backend decision I made on Learnflow AI wasn’t about speed, performance, or even voice logic. It was about simplicity. From the start, I knew two things: Every user should be on a plan (Free or Pro) Every plan should define exactly what features the user could access But here’s the problem: Most tools split these concerns across two completely different services. One API for auth. Another for billing. A third for usage tracking (usually the database). You end up stitching together logic just to answer a question as basic as: "Can this user start a session right now?" Learnflow AI isn’t a typical SaaS app. It’s usage-based, voice-powered, and session-restricted. And to make the experience smooth, I didn’t want 5 lookups across 3 APIs. So I made a bet: What if billing and acce…  ( 8 min )

THINGS I’VE WORKED ON/COMPLETED… The Find method in BST. The levelOrderForEach in BST. In the levelOrderForEach method, I wasn’t entirely sure ‘how much’ should go into the callback (what to put in the callback v the main method, but I realised that if I created the array in the callback, that this would not work as a new array would be created each time. I asked for some advice about this and was told that it was perfectly acceptable for the callback to perform a simple task (console logging nodes visited in this case). I tried to implement recursion in the levelOrderForEach method, but struggled with it - someone suggested to me that recursion might not be the best way to approach BFS, so I went with the iterative approach in the end.

Hey Devs, Dhruv Here. 👋 I've been building software and writing content about it for about 7 years now. I’ve witnessed the evolution of tooling — from writing repetitive code manually to having AI pair-programmers that feel almost magical. 2024-2025 has been a whirlwind for agentic AI. We're not just getting code suggestions anymore — we’re delegating entire tasks to AI-powered agents. In this post, I’m sharing 10 AI agentic tools that I personally find game-changing — the kind that save time, reduce context switching, and let me focus more on architecture and less on boilerplate. Quick detour for clarity — agentic tools are not just passive assistants like autocomplete or chatbots. These are task-completing, goal-oriented AIs. You give them intent (“write tests for this module” or “gener…  ( 7 min )

In my Task Automation API, I added email notification support using Python’s smtplib. The setup is minimal, uses no extra packages, and leverages environment variables to securely manage SMTP credentials. Here’s a breakdown of the implementation, inspired by this commit: View commit on GitHub import smtplib from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart import os def send_email(recipient: str, subject: str, body: str): sender = os.getenv("SMTP_SENDER") password = os.getenv("SMTP_PASSWORD") smtp_server = os.getenv("SMTP_SERVER") smtp_port = int(os.getenv("SMTP_PORT", 587)) msg = MIMEMultipart() msg["From"] = sender msg["To"] = recipient msg["Subject"] = subject msg.attach(MIMEText(body, "plain")) with smtplib.SMTP(smtp_server, smtp_port) as server: server.starttls() server.login(sender, password) server.sendmail(sender, recipient, msg.as_string()) To keep secrets out of the codebase, define these in your .env file or server environment: SMTP_SENDER: Your email address SMTP_PASSWORD: SMTP password or app-specific password SMTP_SERVER: SMTP host, e.g., smtp.gmail.com SMTP_PORT: Port number, usually 587 How I Use It After a user schedules a task, once and it’s validated, I call send_email to notify them: send_email( recipient=current_user.email, subject="File Upload Successful", body=f"Your file {file.filename} was uploaded and verified." ) No external dependencies Secure configuration with environment variables Easy to extend for HTML emails or attachments later Adding SMTP email with smtplib is a lightweight, effective way to send notifications in your FastAPI app. This pattern fits nicely in automation workflows like mine.

AI Copilot or Job Killer? Microsoft's New Report Details the Future of Work In a landmark new report, Microsoft has shed light on one of the most pressing questions of our time: how will generative AI reshape the job market? The tech giant, a key player in the AI revolution, has analyzed the skills and tasks most susceptible to automation. The findings suggest not a simple story of replacement, but a complex evolution where adaptability will be paramount, moving beyond hype to provide a data-driven look at the roles facing the most significant transformation. According to the analysis, roles characterized by repetitive, predictable tasks are most exposed to AI's influence. This is less about entire professions disappearing overnight and more about specific functions within them being automated. Key areas identified include office and administrative support, where tasks like scheduling and data entry are prime candidates for AI assistants, and customer service, where chatbots can handle routine inquiries, freeing up human agents for more complex issues. However, the report emphasizes that this disruption is a double-edged sword. Microsoft frames AI primarily as a "copilot" designed to augment human capabilities, not eliminate them. The key takeaway is a call for a massive shift in workforce skills. The roles least at risk are those that rely heavily on uniquely human traits: critical thinking, complex problem-solving, emotional intelligence, and creativity. The future of work, as envisioned by Microsoft, is one of human-AI collaboration. The challenge now lies in reskilling and upskilling the workforce to thrive in this new, augmented reality.  ( 7 min )

Hey developers! 👋 Today I want to share some insights about the reset statement in Uniface ProcScript - a handy little command that can help you manage function values effectively. With some assistance from AI, I've put together this quick guide based on the official Uniface 10.4 documentation. The reset statement is pretty straightforward - it resets the value of a specified ProcScript function to 0 (FALSE). Think of it as a way to clear or reinitialize certain system functions when you need a fresh start. reset ProcScriptFunction For example: reset $procerror Parameter Data Type Description ProcScriptFunction Literal The ProcScript function you want to reset The $status variable will contain: <0: Reset cannot be used with the specified function 🚫 0: Function was successfully reset ✅ Good news! You can use reset in all component types except: Self-contained Reports 📄 Services 🔧 Here's a real-world scenario where reset comes in handy. Let's say you're working with form modifications: operation exec city = "New Orleans" ; this sets $formmod to 1 reset $formmod ; reset the modification indicator edit NAME end In this example: We modify the CITY field, which automatically sets $formmod to 1 🏙️ We then reset $formmod back to 0 using the reset statement 🔄 Finally, we edit the NAME field 📝 Remember that reset can only be used with functions that specifically support this feature. Always check the documentation for the particular function you're working with! The reset statement might seem simple, but it's a powerful tool for managing state in your Uniface applications. Whether you're dealing with error indicators, modification flags, or other system functions, knowing when and how to use reset can make your code cleaner and more predictable. Happy coding! 🚀 This article is based on the official Uniface 10.4 documentation.  ( 6 min )

(Първо публикувано на 20.01.2017) Днешният алгоритъм е доста интересен и всъщност доста ме плашеше преди време. 😀 Това е един от най-популярните алгоритми за сортиране и е широко използван в практиката, тъй като е подходящ за големи списъци от данни. Това е Quicksort! Погледнете обяснението за QuickSort в AlgoList — голяма част от информацията в този пост е взета от там (страхотен сайт с много добри обяснения за редица популярни алгоритми). ОПИСАНИЕ: Quicksort е алгоритъм за сортиране от тип “разделяй и владей” (разделяме задачата за сортиране на по-малки и накрая обединяваме малките решения в едно голямо). Както казахме, Quicksort е най-подходящ когато искаме да сортираме големи списъци от данни. Средната му сложност е O(n log n), а в най-лошия случай е O(n²), макар че в повечето случаи…  ( 10 min )

When working with Uniface development, one of the fundamental control structures you'll encounter is the repeat/until loop. With the help of AI, I've put together this comprehensive guide to help you understand and implement these loops effectively in your applications. 📚 The repeat/until statement in Uniface creates a loop that executes one or more ProcScript instructions repeatedly until a specified condition becomes TRUE. Unlike other loop types, this guarantees that the code block executes at least once before the condition is evaluated. repeat ... one or more ProcScript instructions ... until (Condition) Condition: A Boolean expression that must evaluate to TRUE to exit the loop Data Type Conversion: Uniface automatically converts any data types in the expression to boolean …  ( 6 min )

Hey developers! 👋 Today I want to share something useful about Uniface development that I've been working with recently. With some help from AI, I've put together this guide about the remocc statement in Uniface 10.4 - a powerful function for managing database entity occurrences. This post is based on the official Uniface documentation 10.4. The remocc statement in Uniface marks an occurrence of a specified entity for deletion at the next store operation. Think of it as marking a database record for removal - it doesn't delete immediately, but flags it for deletion when you perform a store command. remocc Entity, OccurrenceNumber remocc "CUSTOMER", 0 Entity (String): The entity where an occurrence should be removed. This can be a string, field, variable, function, or parameter that ev…  ( 6 min )

JavaScript is a programming language used to make the web pages interactive. It can update and change both HTML and CSS. Data Handling: In JavaScript, it refers to collect,store, process and manipulate data. JS Data types: Big int: It is used for storing big integer values in javascript [Ex:123456789012345678901234567890] In Java,data types can be divided into two groups: primitive and non-primitive. Primitive data types: Identifiers: It is the name which is given to the variables,function,arrays etc. How to declare variable in JavaScript: let name="Vidya"; In Java, the variable can be declared as: string name="Vidya"; Statically typed programming language: If a variable has to be declared, data type must be declared before defining the variables. Dynamically typed programming language: In this, no need of mentioning the type of variable when declaring it.The type is automatically decided at runtime, based on the value assigned. var: It is a keyword used to declare a variable in JS. There are two types of scopes : local scope and global scope. Local scope: In this, a variable can be accessed only inside a specific part of a code like a function. Global Scope: If a variable is declared outside any function using var, it becomes globally scoped i.e, it can be accessed from anywhere in the code. In Java, redeclaration cannot be done, but reinitialization can be done. let: It offers block scope, which means the variable exists only within the {}. let name=John; const: It is used to declare a variable whose value cannot be changed once the value is set. const i = 10; // Error Here, error will occur because a variable declared with const cannot be changed after its initial value is set.  ( 6 min )

While perusing my Masters of Computer Application in Gurugram, I’ve been preparing for coding interviews. It’s been hard but very rewarding. I wanted to get into the tech industry as a full stack web developer, so I decided to step up my study plan by following the famous NeetCode 150 questions list. This list is a carefully chosen set of questions that will help people get ready for software interviews at top tech companies. Why I Picked the NeetCode 150? NeetCode 150 is a full but easy-to-use playlist for anyone who wants to get better at data structures and algorithms. It includes the classic “Blind 75” list and 75 more handpicked questions. It covers all the important topics and groups problems into three levels: Easy, Medium, and Hard. This lets you learn strategically and gradually improve your skills. My Progress So far Learning Highlight: Knowing the ins and outs of two-pointer techniques and recursion has really changed how I solve problems. Some days are hard, especially after a long day of lectures and homework, but sticking to a schedule (my goal is 10 questions per week) keeps me going. Tracking the percent of completion helps you see how far you’ve come and keep going. Doing the code solutions by hand: Reading the NeetCode solution is helpful, but actually writing the code yourself is what really helps you understand. Concentrate on Weak Areas: Are you having trouble with a problem? Put it aside for a week and then look at it again. Stay on track: Even solving one or two problems a day adds up quickly! Don’t Compare Your Progress: Everyone’s path is different. Some days you’ll solve a lot of problems, and other days you’ll only solve one. That’s fine. Happy coding ;-)  ( 6 min )

🚀 Tracking My First 4 Real Users — Lessons from Week 1 of Biz Tracker Hey devs 👋, I’m Prasoon — a 16-year-old developer from India. A few weeks ago, I launched my first real product: Biz Tracker, a browser-based stock and billing web app built for small businesses and indie founders. Since then, I've started seeing real users — not thousands, but enough to start learning. Here’s what my Umami dashboard showed in the last 24 hours: 👥 Total Visitors: 4 📈 Views: 11 🧭 Visit Duration: 3m 2s average ↩️ Bounce Rate: 25% 📱 Devices: 75% Tablet, 25% Mobile 🌍 Countries: 75% India 🇮🇳, 25% United States 🇺🇸 🔗 Referrer: vercel.com Even more interesting — users explored beyond just /stock: /map /about That’s real engagement 👀 Time spent matters more than traffic count People stayed for over 3 minutes — that tells me they’re not just clicking, they’re actually trying the tool. Low bounce = good first impression 25% bounce rate is solid. My landing flow might be working. Curiosity is validation Someone checked /map and /about. That means they were exploring — I should prioritize improving those next. Tablets dominate I designed Biz Tracker to work on mobile, but 75% used tablets. Time to fine-tune tablet experience too. Direct shares drive traffic Most traffic came from Vercel — likely users checking my shared link or deployment. Organic sharing works! Here’s what I’m building next: 🗺️ /map tab update 📈 Better dashboard visuals 🧾 Invoice builder 📤 Data export/download 💬 Feedback button You can: 🧪 Try the app: https://biz-tracker-vert.vercel.app/stock 🗣️ Send feedback (good or bad) 📤 Share with someone who runs a business, startup, or shop Thanks for reading — I’m building in public and learning every day.

When you're learning about databases, one concept you'll hear often is the foreign key. At first, it might sound a bit technical, but don’t worry—I'll explain it in a simple way, with examples, so it sticks. A foreign key is a column (or a set of columns) in one table that refers to the primary key in another table. Think of it as a link or relationship between two tables in your database. ✅ It helps keep your data connected and consistent. Imagine you have two boxes: Box 1: A list of countries with unique IDs (Primary key) Box 2: A list of people, where each person belongs to a country To know which country each person is from, you store the country ID from Box 1 inside Box 2. That country ID in Box 2 is a foreign key. Let’s say we have two tables: countries table CREATE TABLE countr…  ( 6 min )

Working with database operations in Uniface can sometimes feel like juggling multiple balls at once, especially when dealing with concurrent access and record locking. Today, I want to share insights about one of Uniface's essential database statements: reload. 🎯 Note: This article is based on the official Uniface Documentation 10.4, and I had assistance from AI to structure and present this information. The reload statement in Uniface is designed to reread and lock the current occurrence from the database. Think of it as a refresh button that not only updates your local copy of a record but also secures it for your exclusive use. 🔒 The basic syntax is straightforward: reload{/nolock} The optional /nolock qualifier allows you to reread the current occurrence without locking it in the da…  ( 6 min )

Lately, I’ve been reflecting on how we can further optimize software development with AI. And then it hit me—what if we had a workspace, like Trello, specifically designed not just for humans, but to orchestrate collaboration with AI models? https://aifa.dev will have this in its function These days, we often let AI decide how to implement a feature. It feels a little like having a Tesla on autopilot—smooth and automatic, but sometimes you just want more control. What if we gave that autopilot a “manual gearbox”? Picture this: Project Capture: The Trello-like system “swallows” your whole project—files, structure, dependencies. No more “but it works locally.” Micro Changes: Every AI request introduces the smallest possible change. Forget “build the whole component.” Instead: “Add email val…  ( 6 min )

GORM is one of the most popular Object Relational Mappers for Go. It provides a clean, expressive API for interacting with databases, abstracting away much of the boilerplate SQL code while still allowing fine-tuned control when needed. To start using GORM, first install the library: go get -u gorm.io/gorm go get -u gorm.io/driver/sqlite # or another driver like mysql/postgres Then, set up a simple connection: import ( "gorm.io/gorm" "gorm.io/driver/sqlite" ) db, err := gorm.Open(sqlite.Open("test.db"), &gorm.Config{}) if err != nil { panic("failed to connect database") } You define your data structures as Go structs. GORM uses reflection to map these to database tables: type User struct { gorm.Model Name string Email string } Create: db.Create(&User{Name: "Alice", Email: "alice@example.com"}) Read: var user User db.First(&user, 1) // find user with ID 1 db.Where("name = ?", "Alice").First(&user) Update: db.Model(&user).Update("Email", "new@example.com") Delete: db.Delete(&user) Productivity: Less boilerplate, cleaner code. Portability: Works with multiple databases. Flexibility: Lets you drop down to raw SQL when needed. Slightly larger binary size. May not be the fastest for high-performance use cases — consider raw SQL or sqlx if needed. GORM is a great tool for building Go applications that need reliable database interaction with minimal friction. It’s especially useful for rapid development, small to medium-sized apps, and teams looking for readability over raw performance.  ( 6 min )

This is a submission for the Redis AI Challenge: Beyond the Cache. I built a location-aware prayer time web app that delivers three core features: Mosque-Specific Display Each mosque has a unique URL that shows its daily prayer schedule, name, address, and date. The times are accurate based on its stored latitude and longitude. Browser-Based Location Detection When users visit the general homepage (https://redis-prayer-times.netlify.app), the app detects their location using the browser’s geolocation API, fetches their latitude and longitude, and then displays prayer times specific to their location. Nearby Mosque Finder This makes it easy for both mosque administrators and everyday users to access accurate prayer times tailored to their precise location. 🌐 Live Website: General: https://redis-prayer-times.netlify.app Mosque-Specific: Example: Masjid Istiqlal Nearby Mosques: https://redis-prayer-times.netlify.app/nearby-mosque How I Used Redis Cloud This project uses Redis Cloud beyond caching in the following ways: Each mosque's coordinates (latitude, longitude) are stored in Redis using GEOADD, with their mosque ID or name as the key. When a user's location is detected via the browser: The app executes GEOSEARCH to find the nearest mosque(s) within a certain radius (e.g., 5km or 10km). If a nearby mosque is found, the app uses its exact location to fetch the corresponding prayer times. The mosque’s name and address are also displayed to the user. Tech Stack Frontend: Vue.js + Tailwind CSS Backend: Netlify Functions (Node.js) Database: Redis Cloud Deployment: Netlify Geolocation: HTML5 Geolocation API + Redis GEO https://github.com/siswoyo-dev/redis-prayer-times ✅ This app makes prayer time tracking easy, accessible, and personalized — powered efficiently with Redis!  ( 6 min )

“The most scalable systems separate responsibility — and memory.” Modern enterprise systems demand scalability, auditability, performance, and clarity in design. This is where CQRS and Event Sourcing shine. Let's explore what they are, the problems they solve, when to use them, and when not to. CQRS stands for Command Query Responsibility Segregation. It’s an architectural pattern that separates read and write operations into different models. Commands: Change system state (e.g., createOrder, updateUser). Queries: Return system state (e.g., getOrdersByUserId). Instead of using one data model for both, CQRS proposes distinct models — one optimized for writes (commands) and one for reads (queries). Event Sourcing is a pattern where state changes are stored as a sequence of events, not just a…  ( 7 min )

Understanding the Relationship Between Control and Risk Risk management and project control are deeply intertwined. While risk management identifies and analyzes potential threats to a project, the control process provides the framework to track, respond to, and mitigate those risks in real-time. It acts as the operational layer that ensures the strategies defined in the risk management plan are being applied consistently and effectively throughout the project lifecycle. The project control process facilitates early detection of risks through constant monitoring of project performance indicators. By comparing actual progress with planned values, control mechanisms can identify trends that signal the emergence of potential risks.

Here’s a small internal list I keep for clean and stable WordPress setups. Nothing fancy, just things I wish someone had told me earlier :) Go to Settings > Permalinks and choose "Post name". Please don't wait until you’ve created 20 posts to change this. Less is more. Fewer plugins mean fewer problems. Stick to a core stack you trust. I use: Elementor Pro + JetEngine + WP Rocket + Fluent Forms. Unless you’re using remote apps or Jetpack, disable it. Some security plugins allow you to turn it off with one click. Block useless folders like /wp-content/plugins/ and allow only what needs indexing. Don’t block the site by mistake :) You don’t need a fancy staging server: LocalWP or MAMP can save your ass before going live. Simple stuff, but if you apply it early on, you avoid pain later. And if something breaks, fix it… or delete it and pretend it never happened ;) 🌱 Ellie Miguel – elliemiguel.es  ( 5 min )

Starting today, we'll dive deep into a crucial feature of the Dart language — Null Safety. Introduced in Dart 2.12, null safety is a major enhancement that fundamentally changes how we handle null values, making our code more robust and reliable. In this lesson, we'll first understand "why null safety is needed" and its basic concepts. Before learning about null safety, let's clarify one question: Why bother introducing null safety? The answer is simple — to eliminate Null Pointer Exceptions (NPEs). A null pointer exception occurs when you try to access a property or call a method on a variable that has a value of null.

If you’ve ever felt like debugging an Angular app was like solving a puzzle in the dark, you’re not alone. I’ve been there too, opening the browser console, adding console.log() statements, trying to guess why a component keeps re-rendering or where a signal is stuck. That changed when I started using Angular DevTools. In this article, I’ll walk you through how Angular DevTools works, what you can do with it, and how to use it to debug smarter and optimize faster, with practical examples and diagrams to help you visualize what’s happening under the hood. Angular is powerful, but sometimes that power makes things harder to trace. Between @Input() bindings, signals, services, lifecycle hooks and change detection, it can be difficult to see what's really going on. Angular DevTools is a browse…  ( 7 min )

The way we watch television has never stood still. From bulky antennas and limited broadcast hours to on-demand streaming and global access, the evolution has been constant. But nothing has shifted the experience quite as profoundly as artificial intelligence. AI is no longer just a futuristic buzzword. It's already reshaping our viewing habits, often in ways we don’t even notice. It determines what content gets recommended, how it’s presented, and even how we interact with it. Behind the scenes, machine learning models are optimizing every second of your screen time — from quality to context to convenience. This article explores five significant ways that AI is actively transforming how we watch TV. Whether you’re a casual viewer or a passionate binge-watcher, it’s becoming clear that the…  ( 8 min )

Another day, with react trying to rewire my brain. Started this morning at 8 AM with what I like to call "heat therapy" (okay, it's just a hot water bottle, but it sounds more professional). Finally dove deeper into React today, and let me tell you - it's like learning a new language where every word has seventeen different meanings depending on the context. My head feels like it went through a blender, but the good kind of blender where you might actually emerge with a smoothie brain that understands component lifecycles. The plan is to wrap up React tomorrow and jump into Tailwind CSS. Because apparently, my brain needed more styling frameworks to juggle alongside everything else I'm trying to cram in there. Made it to the library with my umbrella, which performed slightly better today. Still got drenched, but hey, improvement is improvement, right? There's something about the library environment that just makes you want to actually get stuff done, even when your brain is protesting every new concept you're trying to shove into it. Had one of those moments while heading to the library where I thought, "why can't I just marry rich and skip all this?" But then reality kicks in - apparently, it's the guys' job to mess themselves up with work (thanks, society). Spontaneously created a team for an ideathon today. Called it "timepass" but we both know how these things usually end up. One minute you're just participating for fun, the next minute you're three days deep Tackle Tailwind CSS (because my brain clearly needed more frameworks) The learning curve is steep, the concepts are multiplying faster than I can process them, and my umbrella skills are marginally improving. What more can you ask for in a day?  ( 6 min )

Someone I know forged attendance records for weeks, possibly months. Their log in time in the WhatsApp attendance group was 9:30 am but in the actual biometric device, their log in time was 9:50 am. They also left early on several days after taking permission from the manager but never documented it in the attendance group (only 2 hours of permission is allowed per month). And they took second half leaves and did not document it in the WhatsApp attendance group and did not log out in the biometric device on those specific days. Do you think what they did was unethical? Do you think what they did was fraud? And the company did not take any action on them. Do you think that is morally responsible? This leaves me with these questions for the person involved: Is your character's worth equivalent to half a day's salary? Can you sleep at night knowing that you cheated the very people you spent the whole day with? Do you think it is fair that you get away with such things whereas other people honestly track their time, hours and leaves? This leaves me with these thoughts regarding the person involved: Did they grow up thinking that unethical things are okay as long as you don't get caught? Are their actions a direct reflection of their upbringing? In their mind, do they think they did not do anything wrong? Maybe because they have done it so many times and haven't gotten caught. And these are my thoughts about the way the management handled the situation: Is inaction in such a situation a result of a lack of moral courage? Is it fair to other employees who are honest? Inaction in such a situation creates resentment among honest people. Inaction in such a situation is a way to reward dishonesty and punish honesty.

As developers, we rely heavily on API platforms to test, document, and manage our services. For years, Postman has been the preferred tool. However, lately, Apidog has been gaining popularity as a modern alternative. So… which one should you choose? Pros: Mature ecosystem with extensive integrations. Rich support for automated testing and monitoring. Great collaboration features via Postman Workspaces. Large community and documentation. Cons: Heavier UI, can feel slow for basic tasks. Some advanced features are locked behind a paywall. Pros: Combines API testing + documentation + mock + management in one UI. Native OpenAPI/Swagger-style workflow. Lightweight, clean interface. Faster performance in many cases. Cons: Smaller community and fewer integrations (for now). Still evolving—some features might feel beta-like. If you're working in a team with deep integration needs, Postman remains a strong choice. However, if you're looking for a fast, modern tool that seamlessly integrates API documentation and testing with minimal overhead, Apidog might surprise you. I’m starting to reach for Apidog on new projects—especially solo or small-team builds. It just feels… smoother. Follow @mahmud-r-farhan for more!  ( 5 min )

Many small businesses think cyberattacks won’t happen to them. But hackers often target small companies because they know the defenses are weak. One mistake can lead to stolen data, lost customers, and legal trouble. This guide shows easy ways to protect your network using basic tools. Weak passwords are easy to guess. If you use something like password123 or the same password on every account, you’re making it easy for hackers. Use different passwords for each account. Make them long—at least 12 characters. Mix letters, numbers, and symbols. For example, Tr!ckH0use_94# is way better than admin123. Don’t try to remember them all. Use a password manager. It stores your passwords safely.

My take on the Andy Byron Coldplay incident: We see that Andy Byron got a lot more heat than Kristin Cabot for what happened at Coldplay. Do you know why? Because he is at more fault. First off - why do I say he got more heat? Because he is the one that the social media people cannot stop talking about. His wife's reaction is more discussed than Kristin's husband's reaction. And now - why is he more at fault? Because he was in a position of power and he misused it. Andy Byron as the CEO of Astronomer had a lot more power than any other employee in the company and he chose to use that power to seek an inappropriate and unethical relationship with another employee in the company who worked below him. Any one is Kristin's place would have felt coerced to go along. That is not an affair, that is coercion and harassment. And she is not a singular woman in this situation. Many women all over the world feel obliged to stay in inappropriate relationships because of power imbalance and fear of losing their jobs. And he is certainly not a singular man in this situation. Many men abuse their positions of power to get what they want. Some might argue that she looked too happy in the video for it to be coercion. To them, I'd like to say this - once you make a decision, your mind makes peace with it, it becomes your reality and instead of being unhappy all the time, your brain accepts your reality and stays happy even in difficult situations that you'd rather not be in. That's resilience.  ( 6 min )

Weekly Challenge 332 Each week Mohammad S. Anwar sends out The Weekly Challenge, a chance for all of us to come up with solutions to two weekly tasks. My solutions are written in Python first, and then converted to Perl. It's a great way for us all to practice some coding. Challenge, My solutions You are given a date in the format YYYY-MM-DD. Write a script to convert it into binary date. For this task, I do these steps. Split the date from input_string on hyphens into the date_parts list (array in Perl). Convert each part from an integer to binary value. This is stored as binary_parts. Join the binary_parts list in a single string separated by hyphens. Python def binary_date(input_string: str) -> str: date_parts = input_string.split('-') binary_parts = [bin(int(part))[2:] for part in date_parts] return '-'.join(binary_parts) Perl sub main ($input_string) { my @date_parts = split /-/, $input_string; my @binary_parts = map { sprintf( "%b", $_ ) } @date_parts; say join( '-', @binary_parts ); } $ ./ch-1.py 2025-07-26 11111101001-111-11010 $ ./ch-1.py 2000-02-02 11111010000-10-10 $ ./ch-1.py 2024-12-31 11111101000-1100-11111 You are given a string. Write a script to find out if each letter in the given string appeared odd number of times. Python has the Counter method that will convert an iterable (like a string) and create a dictionary with the frequency of each letter. I then use the all function to check if all letters occur an odd number of times. def odd_letters(input_string: str) -> bool: freq = Counter(input_string) return all(count % 2 == 1 for count in freq.values()) Perl doesn't have an equivalent of the Counter function, so I do that part by hand. sub main ($input_string) { my %freq = (); for my $char ( split //, $input_string ) { $freq{$char}++; } my $all_odd = all { $_ % 2 == 1 } values %freq; say $all_odd ?

Hey Dev community 👋 I’m Bhanu, currently working in customer support role, and today I’m finally doing what I always dreamed of — learning to become a developer. I didn’t grow up with access to modern computers or tech. I come from a remote village in India. My journey with technology started on a ₹500 keypad phone when I was about 10–12 years old. Somehow, I managed to download newly released movies, Java games, and explored every corner of that tiny device. Tech always fascinated me. Later, when I got a Nokia Windows phone in class 10th, I turned it into a mock Android using launchers and tweaks. I figured out how to run games that weren’t even supported or released in India. Family and friends always came to me for fixing phones or tech issues. Despite never owning a laptop, I learned more about computers and systems than most people around me. I’m not saying this to boast — it’s just who I am. I’m curious, a fast learner, and I like breaking down problems to the fundamentals. Things I’ve taught myself: Solved a Rubik's cube within minutes Learned Sudoku in few hours Can play chess and guitar Now: diving into front-end development I recently purchased a MacBook, downloaded VS Code, built a simple portfolio site, and started learning HTML & CSS with freeCodeCamp. This blog is the first of many. I’ll be sharing my learnings here. If you're on a similar path or made the switch from a non-tech role — I'd love to hear your story too.

As developers, we’ve all said it: “I’ll finish my portfolio this weekend.” That’s why I decided to build a lightweight, ready-to-use portfolio template — and share it with the community. I needed a personal site that: Looked clean and modern Loaded fast on all devices Included smooth animations Was quick and easy to customize Most templates I found were bloated, overly complex, or simply not developer-friendly. So I created my own — built with simplicity and flexibility in mind using: HTML – for clean structure Tailwind CSS – to build fast with utility-first classes GSAP – for subtle, scroll-based animations A responsive layout that works on all screen sizes Scroll-triggered GSAP animations Clean, semantic HTML Utility-first styling with Tailwind Pre-built sections: Hero, About, Projects, Contact You can clone it, customize it, and make it your own — whether you’re applying for your first dev job or refreshing your freelance brand. Front-end developers who want to skip boilerplate Freelancers who need a fast, stylish portfolio Students and job seekers building their personal brand Anyone who wants to ship faster and stand out I’ve made the template available on a platform where you can preview it, grab the files, and start customizing. Grab Now Thanks for reading! Hope this helps you finally finish (or start) that portfolio project you’ve been putting off. Feel free to share how you customize it — I’d love to see what you build.  ( 6 min )

I’ve been writing and reviewing Go code for a while now - from building backend services to contributing to open-source projects. One thing I’ve learned the hard way is that insecure code doesn’t always look "wrong" - sometimes it looks completely ordinary. In this post, I want to share five common patterns I keep seeing in real-world Go codebases that can easily turn into serious security issues. These aren’t exotic bugs — they’re patterns that show up quietly, subtly, and often go unnoticed in PRs, even by experienced teams. Let’s start with the classic: query := fmt.Sprintf("SELECT * FROM users WHERE email = '%s'", email) Even if email is sanitized upstream, or “should never come from user input”, you’ve just opened the door for SQL injection.

Some time ago I completed the CodeCrafters BitTorrent challenge, and after that I rewrote the torrent client in Blazor to understand it more deeply and also as a portfolio project. So I chose Blazor rather than going with .NET MVC. I took on this project to enhance my C# skills and logic, and I learned more about how cryptography works, networking, TCP handshake, and obviously how BitTorrent files work. This article isn’t a deep dive, but rather a quick overview of how I built the BitTorrent client and how it works under the hood. BitTorrent files are decoded using bencoding, and you have to decode this format to get the file contents. Bencoding supports 4 types, and they are encoded like below: Integers are encoded as ie. Zero is encoded as i0e. Byte Strings are enc…  ( 7 min )

Today, we'll dive deeper into two other core features of object-oriented programming — inheritance and polymorphism — along with the use of abstract classes and interfaces. These features help us build more flexible and scalable code structures. Inheritance allows one class (child class) to inherit properties and methods from another class (parent class), while adding new properties/methods or modifying parent class methods. This greatly improves code reusability. Use the extends keyword to implement inheritance: // Parent class (base class) class Animal { String name; int age; // Parent class constructor Animal(this.name, this.age); // Parent class methods void eat() { print("$name is eating"); } void sleep() { print("$name is sleeping"); } } // Child class (…  ( 10 min )

Gardening is a rewarding hobby, but plant diseases can be frustrating, especially when you notice rust spots spreading across your leaves. Rust is a fungal infection that weakens plants by reducing photosynthesis, eventually affecting blooms and harvests. The good news? You can treat rust organically without relying on harsh chemicals. Here are five effective, eco-friendly methods to protect your garden. As soon as you notice rust spots, remove the infected leaves and dispose of them in the trash (not the compost bin). This stops the fungus from spreading to healthy parts of your plant. Fungal infections thrive in damp, crowded spaces. Spacing your plants properly and lightly pruning can increase airflow, making it harder for rust to survive. Wet leaves are a playground for rust fungi. Instead of overhead watering, water at the base of your plants early in the morning. This keeps leaves dry and reduces fungal growth. Homemade sprays like baking soda solution (1 tsp per quart of water with a few drops of dish soap) can help slow fungal growth. Neem oil is another organic fungicide that’s safe for most plants and highly effective against rust. Healthy plants resist diseases better. Add compost, worm castings, or compost tea to improve soil health, giving your plants the nutrients they need to fight off infections naturally.

Your CV isn’t a memoir — it’s a spec sheet. I’ve been on both sides of the hiring table in tech and I keep seeing the same issues crop up again and again. So I decided to condense everything I’ve learned into one clear and simple guide. As a bonus, I put together a CV template to go with it. Use a clean, readable format (no fancy colours, no 2-column designs). Lead with your impact. Show what you did, not what you were “responsible for”. Quantify everything: “improved p99 latency by 80%”, “increased conversion by 1.5%”. 1–2 pages max. PDF only. Use a real filename. Tailor your CV to the role (and stack) you’re applying to. I’ve turned this advice into a downloadable Google Docs template you can copy and make your own. It’s based on my own CV so it’s tried, tested, and continuously improved. Link: Download the CV Template If you want the full article that goes into CV anatomy, red flags to avoid, and formatting tips, I’ve written that up here: How to Write a Great Software Engineering CV Your CV’s only job is to earn you a conversation.

Nullsafe Operator (?->) ✅ Purpose: Safely access a property/method only if the object is not null. // Without nullsafe $name = $user && $user->profile ? $user->profile->name : null; // With nullsafe $name = $user?->profile?->name; ✅ Use it to simplify deep object access that might be null. Named Arguments ✅ Purpose: Call functions using argument names instead of relying on order. Named arguments were introduced in PHP 8.0, released on November 26, 2020. ✅ Key Details: Order doesn't matter, as long as required arguments are passed. Great for optional parameters and readability. function sendMail($to, $subject, $message) {} sendMail( to: 'user@example.com', message: 'Hello!', subject: 'Welcome' // ✅ Order doesn’t matter! ); e.g : function createUser(string $name, int $age, string $role = 'user') { return "$name is $age and has role $role"; } echo createUser(age: 25, name: 'Raza', role: 'admin'); ✅ Great for readability, especially with many optional parameters. Constructor Property Promotion ✅ Purpose: Auto-declare and assign class properties from the constructor. old way : before php 8.0 class Product { public string $name; public int $price; public function __construct(string $name, int $price) { $this->name = $name; $this->price = $price; } } new way: not support for previos versions of php before 8.0 class Product { public function __construct( public string $name, public int $price ) {} } 🧠 Benefits: Makes class definitions cleaner and easier to read. Supports visibility modifiers (public, protected, private) and default values. 🔍 Notes: Works with typed properties (which were introduced in PHP 7.4). Promoted properties must have a visibility modifier (public, private, or protected).  ( 6 min )

Working on my MERN stack project (which I will reveal in the future), I came across an issue that almost everyone faces at least once when dealing with Mongoose and MongoDB queries. It happens when we query some result from MongoDB, and the result contains sensitive information that we do not want to share with the client. I searched for solutions and found some simple ways to avoid this: ._doc object from the MongoDB response if (newUser) { const { password: pwd, ...responseData } = newUser._doc; // <-- res.status(201).json({ msg: "User created successfully.", user: responseData // user: newUser }) } Here, by using the ._doc object, you can separate the password from the rest of the data and return only the safe response data, without worrying…  ( 6 min )

Ever have an idea for a web app but get bogged down by the setup before you even write a single line of application code? I’ve been there. This time, while catching up on the F1 highlights from last weekend’s race, I decided to try something different. I built a single-page web application that queries a GraphQL API, and I did it almost entirely within the Amazon Kiro IDE, leaning heavily on a concept called spec-driven development. This is the story of how I went from a simple idea to a solid architectural plan in minutes. My journey started with a chat. Not with a colleague, but with Kiro.

Open your LinkedIn feed. You'll see a sea of professional headshots, all blending into a uniform blue and white landscape. But every so often, a profile picture catches your eye. It has a subtle ring of color, a word, or a simple design. That small detail is a LinkedIn Frame, and it’s one of the most underutilized tools for personal branding on the platform. While LinkedIn offers default frames like #OpenToWork or #Hiring, they are generic. Imagine, instead, a frame that uses your brand's colors, promotes your latest project, or announces your role as an event speaker.

In a recent project, I refactored a custom ERP system that had grown over two years. It was time to clean up the monolithic structure and prepare it for scale. Here's how I redesigned the architecture using a modular approach with Laravel 10 and PHP 8.2. As more features were added—purchase inquiries, document management, RFQ workflows, role permissions—the codebase started feeling heavy. Controllers became bloated. Files were scattered. We needed a better way to scale without chaos. I used nWidart/laravel-modules, a well-maintained package that enables Laravel to support modular structure out of the box. Each feature was moved into its own module: Inquiry module – manages purchase requests and workflows Document module – handles categorized file uploads (tech, inquiry, PO, etc.) RFQ modules – separate for Sales and Procurement User & Roles module – integrated with Spatie Permissions 🛠️ Key Tools & Techniques Service-Repository Pattern for separation of concerns Swagger/OpenAPI for documenting each module's API Laravel Sanctum for secure authentication Spatie MediaLibrary for handling file uploads Custom Middleware for module-based permissions Database migrations scoped per module After refactoring: The codebase became easier to test and extend Teams could work in parallel on isolated modules Adding new features doesn’t require editing 10 unrelated files CI/CD pipeline was adjusted to test modules independently If you’re building a long-term Laravel project with growing complexity, don’t wait too long to go modular. It’s an upfront effort, but it pays off as your system scales. Let me know if you'd like me to share a sample structure or even turn this into a starter template.

The standard process for compiling and installing an application from source usually follows these steps: Download and Extract: Download the source code, which is usually a compressed archive (.tar.gz, .tar.bz2, etc.). Configure: Run the ./configure script (if it exists) to check for dependencies and prepare the Makefile. ./configure Compile: Run the make command to compile the code. make Install: Run sudo make install to install the final binary and its associated files to the system. sudo make install Important Note: Always check the README or INSTALL files that come with the source code, as the build process can vary significantly between projects. For local installation ./configure --prefix=$HOME/.local make make install Cmake Build software application using CMake: mkdir build cd build Configure with a CMAKE_INSTALL_PREFIX: You specify the installation directory when running cmake. cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/.local The .. tells cmake to look for the CMakeLists.txt file in the parent directory. Compile and Install: make make install Making the Binaries Accessible After a local installation, the executable files are in a directory like ~/.local/bin, but your shell might not know where to find them. To fix this, you need to add this directory to your PATH environment variable. You can do this by adding the following line to your shell's configuration file (e.g., ~/.bashrc or ~/.zshrc): export PATH=$HOME/.local/bin:$PATH  ( 6 min )

Today, we'll dive into advanced function features — higher-order functions and closures. These are core concepts in Dart's functional programming paradigm, making code more concise and flexible, and are essential techniques in Flutter development. A higher-order function is a function that can accept other functions as parameters or return a function as a result. Simply put, it's a function that "operates" on other functions. When functions are passed as parameters, we can abstract common logic, making functions more extensible. Example: Generic Calculation Framework // Higher-order function: accepts two numbers and an operation function void calculate(int a, int b, int Function(int, int) operation) { int result = operation(a, b); print("Calculation result: $result"); } // Define spec…  ( 9 min )

🌎 Introduction Deploying a Go Echo application to AWS Lambda allows you to leverage a serverless architecture – no server management, auto-scaling, and pay-per-use pricing. Traditionally, Echo apps run as HTTP servers on their own ports, but Lambda functions are invoked by events (like API Gateway HTTP requests). In this guide, we’ll integrate the Echo framework with Lambda’s API Gateway event trigger, enabling your existing routes to run on Lambda with minimal code changes. We assume you already have a Go Echo app (or at least basic familiarity with Echo) and focus on adapting it for serverless deployment. Running Echo on Lambda brings the benefits of quick scaling and minimal idle cost. Thanks to Go’s fast startup and the efficiency of Echo, the performance overhead is small – Go is a…  ( 18 min )

Ever wondered how applications know your API keys, secret tokens, or database credentials without hardcoding them into your code? That magic comes from environment variables. And in many modern web development projects (especially in Node.js, React, Next.js, etc.), we use .env and .env.local files to store these values. Let’s break down what these files are, why they’re important, how they’re different, and some best practices to follow! A .env file is a simple text file that stores environment variables in a key-value format. Example: DATABASE_URL="postgres://user:password@localhost:5432/mydb" API_KEY="12345-abcdef" PORT=3000 These variables can then be accessed inside your app using tools like dotenv in Node.js or automatically in frameworks like Next.js, React, or Vite.

Introduction Nuclear bombs are among the most powerful and destructive technologies ever created. Capable of annihilating entire cities in seconds, their existence has shaped the course of history and global politics since World War II. But behind their unimaginable force lies a deep well of physics, from atomic structure to chain reactions and nuclear fusion. This article explores how nuclear bombs work, the science that powers them, and the difference between their main types. At their core, nuclear bombs release energy stored in the nuclei of atoms, the tiny centers of matter that contain protons and neutrons. This energy comes from either splitting heavy atoms apart (called fission) or fusing light atoms together (called fusion). In both cases, the process converts a small amount of …  ( 7 min )

As the world advances technologically (and Guyana along with it), it is imperative that development does not happen in silos. Every sector, whether it be agriculture, education, health, governance, or others, relies on technology to grow, connect, and deliver. But for effective digital transformation to truly succeed in Guyana, I believe we need more than scattered projects and isolated initiatives. We need a unified national strategy, a National Digital Development Agenda. This agenda would serve as a cross-sector plan that unifies ministries, agencies, and communities under one shared vision for digital progress.

Timeshift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored at a later date to undo all changes to the system. Timeshift is designed to be flexible. When you configure a new backup location, it doesn't just dump all the files in the root of the drive. It creates a dedicated folder structure that is unique to the operating system it's backing up. This is what makes it safe to use a single external drive for multiple systems. Timeshift's Magic: Timeshift is smart enough to see that the timeshift directory already exists on the drive. It will then create a new subdirectory inside of it to store the backups for the second computer. For example, your external drive's folder structure will look something like this: Timeshift-Backup/timeshift/ The hostname1 and hostname2 folders are created automatically by Timeshift to separate the backups for each machine. This ensures there are no file conflicts or overwrites. Create the First Snapshot: After configuration, create your first snapshot on Computer 2.  ( 5 min )

Problem Teams using Amazon Redshift often struggle with a paradox: they know Redshift excels at analytical workloads and can support focused data marts, but when it's time to build one, they face decision paralysis. Should they create a full enterprise data warehouse? Use flat tables? Which Redshift features actually matter? The lack of clear, practical guidance leads to projects that either become overly complex with unnecessary ETL pipelines and modeling layers, or overly simplistic with denormalized tables that become unmaintainable as data grows. A data mart is a subject-focused subset of your organization's data designed to serve specific analytical needs—think sales performance, customer behavior, or financial reporting. Unlike a comprehensive data warehouse that tries to model eve…  ( 10 min )

As developers, we love to build. We love solving complex problems with elegant code. What we don't always love is the "other stuff" that comes with shipping a project—like SEO. And let's face it, manually writing a dozen meta tags for every single page is tedious, repetitive, and easy to get wrong. I can't count the number of times I've launched a personal project, shared it on Twitter, and been greeted by a blank, ugly link preview. Why? Because I forgot to add the right Open Graph or Twitter Card tags. It’s a small detail, but it makes your project look unprofessional. This exact frustration is what led me to build a simple solution. Before I show you the solution, let me briefly introduce the project it's a part of.

Today we're going to learn about functions - the smallest unit of code reuse in Dart. Functions are like "code modules" that encapsulate reusable logic, making programs more concise and maintainable. A function is a block of code that performs a specific task. In Dart, defining a function requires specifying its return type, name, parameter list, and body. returnType functionName(parameterList) { // Function body (code to execute) return returnValue; // Must match returnType } Return Type: If a function returns a value, specify its type (e.g., int, String). If it doesn't return a value, you can omit the type or specify void. Function Name: Follows camelCase naming convention (starts with lowercase, subsequent words start with uppercase), like calculateSum or printMessage…  ( 9 min )

It started with a YouTube tab open. I was watching the Pragmatic Engineer interview with Kent Beck, and something he said I agreed with: Test driven development (TDD) is a “superpower” when working with AI agents. AI agents can (and do!) introduce regressions. An easy way to ensure this does not happen is to have unit tests for the codebase. Kent Beck - Pragmatic Engineer Podcast I see this time and time again in my own use of AI coding agents. At times they are extremely helpful and get the task done as asked, other times they go off the rails and end up breaking everything. The only tool that I know of to help keep them on track is TDD, the "superpower" Kent Beck talked about during his interview. After watching the interview and noodling on the idea of how to keep agents on track, this …  ( 11 min )

Today we'll be learning about extremely important collection types in Dart. In this lesson, we'll focus on List and Set - powerful tools for managing and manipulating multiple data items efficiently in your programs. A List is the most commonly used collection type in Dart. It's an ordered and allowing duplicates collection of data, similar to arrays in other programming languages. There are several ways to create a List, with these being the most common: Method 1: Using literals (Recommended) void main() { // Create a list of integers List numbers = [1, 2, 3, 4, 5]; // Create a list of strings List fruits = ['Apple', 'Banana', 'Orange']; // Create a list with mixed types (not recommended, specify types when possible) List mixed = [1, 'hello', true, 3.14…  ( 10 min )

Lately, whenever I try to use a date picker in a project, I run into two main issues: The default browser feels outdated, inaccessible, and not intuitive enough for modern UIs. External UI libraries often come with bloated bundle sizes and tightly coupled components, making my app unnecessarily heavy. While working on a project at my company, I needed a simple, flexible, and lightweight date picker that could be styled easily — and nothing quite fit. So, I built Byte-DatePicker. ✨ Introducing Byte-DatePicker Byte-DatePicker is a reusable React component library tailored for date selection in forms and dashboards. Written in TypeScript, It allows full date selection (day, month, year) and ships with smooth animations, responsive layout, and minimal styling — making it easy to plug i…  ( 6 min )

Title: The Mind-Bending Reality of the Self: How Our Brain Creates Our Identity Have you ever wondered if the "you" you feel so certain about is just an illusion? In her groundbreaking book, "The Self Illusion: How the Brain Creates the Mind," author Annaka Harris argues that our brain's constant dialogue with the world creates a shifting process, not a fixed identity. This means that our choices, memories, and place in nature are all shaped by our brain's perception of the world around us. Harris's discovery challenges our traditional notions of self and identity, and forces us to rethink how we see ourselves in the world. She argues that our brain's default mode, which is responsible for our thoughts, emotions, and perceptions, is constantly in a state of flux. This means that our sens…  ( 6 min )

📊 Part 2: After building the data collection tool, I had my neatly packed .npz and .mp4 files. But then came the real question: "Now that I’ve collected the data, how do I make sense of it?" So I set out to build a set of tools that would help me not just review the data — but actually understand it. What came out of that is something I’m really proud of. This tool is all about feeling the data, one sample at a time. The desktop GUI is built with Tkinter and designed to make browsing, filtering, and understanding each entry as intuitive as flipping through photos. Use Prev/Next buttons (or arrow keys) to flip through samples. Apply filters for phases and keys — e.g., only show 'press' events where 'd' was active. It even includes broken or empty samples if you want — great for debugging.…  ( 9 min )

What is @preconcurrency? @preconcurrency is a Swift attribute that was introduced in Swift 5.5 alongside the major concurrency overhaul that brought us async/await, actors, and structured concurrency. It was added specifically to solve the chicken-and-egg problem of adopting modern concurrency: how do you use Swift's new concurrent features when most of your existing code and dependencies weren't designed with these strict safety rules in mind? The attribute serves as a compatibility bridge, allowing developers to gradually migrate to Swift's concurrency model without having to rewrite everything at once or deal with an overwhelming number of compiler warnings. When Swift 5.5 introduced structured concurrency, it came with strict rules about what types can safely cross concurrency bounda…  ( 7 min )

🔑 Token-based authentication has become the standard for modern web applications and APIs. If you've ever wondered why we need both access tokens and refresh tokens, or how they work together to create secure, scalable authentication systems, this article will break it down for you. Token-based authentication is a stateless approach to user authentication where the server generates a cryptographically signed token after successful login. This token contains encoded user information and is sent with every subsequent request to prove the user's identity. Traditional session-based authentication relies on server-side storage: 👤 User logs in → 🖥️ Server creates a session → 🍪 Session ID stored in cookie 📨 Each request includes the session ID → 🔍 Server looks up session data 💾 Requires se…  ( 9 min )

Resource tagging is crucial for AWS cost management, security, and governance. Untagged resources can lead to unexpected costs and make it difficult to track resource ownership. Here's a Python script that scans all AWS regions to find untagged resources. AWS resources without proper tags create several issues: Cost tracking: Can't allocate costs to projects or teams Security: Difficult to identify resource owners Compliance: Many organizations require mandatory tags Cleanup: Hard to identify unused resources This Python script uses boto3 and concurrent processing to efficiently scan all AWS regions for untagged resources. #!/usr/bin/env python3 import boto3 from concurrent.futures import ThreadPoolExecutor, as_completed def get_untagged_resources_in_region(region): untagged = [] …  ( 7 min )

In the world of scalable microservices, messaging systems are crucial for decoupling services, improving resilience, and handling asynchronous workloads. Two popular tools that integrate seamlessly with Spring Boot are: Apache Kafka Let’s explore how they work, their differences, and how you can integrate both with Spring Boot. 📌 What is Apache Kafka?

OpenAI's decision to halt Google indexing for ChatGPT highlights the critical balance between user privacy and AI innovation. OpenAI has recently made a significant change to its ChatGPT platform by discontinuing the option for users to have their chats indexed by Google and other search engines. This decision comes in response to user backlash concerning privacy and data security, raising important questions about the implications of AI interactions in the digital landscape. Initially, OpenAI introduced the indexing option to enhance the visibility of user interactions with ChatGPT, allowing users to share insights or information gleaned from their conversations. However, this feature quickly became a point of contention. Users expressed concerns that their private discussions could be in…  ( 7 min )

At RecomendeMe, we believe a single recommendation can change your day — or even how you see the world. This idea inspired the creation of our Cultural Feed, a new way to showcase recommendations for movies, books, music, podcasts, events, or any cultural expression that makes sense for each person. When I first designed RecomendeMe, I noticed that most recommendation platforms treat content as generic — buried in endless lists or algorithmic carousels. I wanted the opposite: every cultural recommendation should stand out like a magazine cover, not get lost in the noise. The Cultural Feed is the dynamic heart of RecomendeMe. Each recommendation has its own space, like a feature cover. The design highlights cover images, short synopses, and direct links to streaming platforms, bookstores, or playlists. The feed is personalized based on each user’s tastes and interactions — the more you like, recommend, and explore, the more relevant your feed becomes. From a technical perspective: Backend: We use PHP and MySQL to manage tables for recommendations, users, likes, and comments. Frontend: We built the feed with HTML, Tailwind CSS, and JavaScript to deliver a fast, responsive experience on both desktop and mobile. Each recommendation is fetched dynamically based on interest filters (e.g., genre, preferred platform, interaction history). Unlike generic feeds, here every item is treated as a highlight. When a user shares a movie, book, or album, it doesn’t disappear into the void — it gets real visibility, and can even become a trend within the community. If you’d like to learn more, share thoughts, or even contribute: let’s connect! 🌐 RecomendeMe — where every recommendation counts.  ( 6 min )

Almost a year passed before I began developing the plugin to improve the security of Infrastructure as Code files. Many rules were implemented, especially for Docker and Dockerfiles, and many lessons were learned. This week, I found new energy to begin delivering the next milestone in the plugin’s lifecycle. I started implementing Kubernetes rules to align with the NSA Kubernetes Hardening Guide. I have always postponed implementing rules to analyze YAML files because it was struggling boring. There wasn’t an API to implement it easily – just brutal PSI analyze. I thought so, but then I found useful classes and methods in the YAML plugin and wrote a simple YAML-path engine to find elements in the text more comfortable. This approach helps me rewrite some smell parts in Docker Compose analy…  ( 7 min )

In this post, I’ll show you how to use ESLint and Prettier in a Nuxt 4 project, step by step. Follow the @nuxt/eslint documentation if you want more details. Run this command in your project: npx nuxi module add eslint If you’re using TypeScript, make sure to install it too: npm install -D typescript After this, you’ll see: The @nuxt/eslint module added in your nuxt.config.ts. A new eslint.config.mjs file generated for you. // @ts-check import withNuxt from './.nuxt/eslint.config.mjs' export default withNuxt( // Add your custom ESLint config here ) Install the dependencies: npm install -D prettier eslint-config-prettier eslint-plugin-prettier Create a .prettierrc file at the root of your project. Example config: { "semi": false, "singleQuote": true, "tabWidth": 2, "trailingComma": "none", "printWidth": 100 } Then update your eslint.config.mjs to use the Prettier plugin: // @ts-check import withNuxt from './.nuxt/eslint.config.mjs' import eslintPluginPrettierRecommended from 'eslint-plugin-prettier/recommended' export default withNuxt([eslintPluginPrettierRecommended]) Add some scripts in your package.json to make it easy to lint and format your code with one command. { "scripts": { "lint": "eslint .", "lint:fix": "eslint . --fix", "format": "prettier --check .", "format:fix": "prettier --write ." } } To make ESLint and Prettier work properly, set up your editor (like VS Code) with the right settings. Install the ESLint and Prettier extensions, and enable format on save to keep your files clean automatically. If you’re using VS Code, you can create a .vscode/settings.json file like this: { "editor.defaultFormatter": "esbenp.prettier-vscode", "editor.formatOnSave": true } Now your Nuxt 4 project has ESLint and Prettier to keep your code clean and consistent.

The first lesson on Javascript30 is building a drum kit, its a really fun project, here's a summary of how it works. First we need to created nine(9) divs to represent all the sounds present. The sounds are all different, each div represents a sound, to actually play the sound we need to create 9 audio elements. One important thing in the div elements is the addition of custom attribute using the 'data-' attribute . In this project we added the KeyboardEvent.code value of every letter as an attribute to it. After creating the all HTML elements and styling with CSS, the major task is the functionality: for the Javascript code, three(3) main functions are needed: The first function is the playsound function. The second is the addTransition function. Then the removeTransition function. The playSound function will be a callback function in the keydown event listener. The addTransition function adds the class "playing" to any div that was clicked to give it that nice quick bouncy transition. The removeTransition function as the name states removes the transition on any clicked element by removing the class "playing". Its passed as a callback function to the "transitionend" event listener. After creating all three(3) functions we'll create the keydown event which calls the playsound function . that's all guys, you've successfully created a drumkit. wesbos for creating such an amazing resource. javascript30 to join me in sharpening your javascript skills. ✌️  ( 6 min )

As a problem solver, we know a few things like Basic Statistical Analysis (like calculating Mean and Standard Deviation): import numpy as np returns = [0.01, -0.02, 0.03, 0.015, -0.005] mean_return = np.mean(returns) print(f"Mean Return: {mean_return:.4f}") std_dev = np.std(returns) print(f"Standard Deviation: {std_dev:.4f}") Or maybe consider a situation like using a CSV file: import pandas as pd data = pd.read_csv('stock_data.csv', par…  ( 7 min )

Have you ever found yourself knee‑deep in a JavaScript app, following a trail of require() calls like breadcrumbs to figure out how everything fits together? One module imports another, that module reaches for a global, and before long you’re chasing references across half your codebase just to test a single component. It’s like cooking a dish where every ingredient is hidden in a different cupboard—you waste half your time hunting instead of actually cooking. That’s precisely the problem dependency injection tries to solve: instead of each class foraging for its own ingredients, you tell a central kitchen what you need, and it hands you the ingredients on a silver platter. The idea isn’t new. In fact, languages like Java and C# bake dependency injection (DI) into their frameworks. Service…  ( 9 min )

Когато сте въвеждали текст на български език ползвайки кирилска клавиатурна подредба като БДС или фонетична, то навярно сте забелязали, че с тези подредби не може да се въвеждат някои символи като квадратни и къдрави скоби ([] и {}). Разбира се това не е пречка да се ползват кирилските клавиатурни подредби. Неудобство е обаче, ако искате да програмирате на JavaScript ползвайки подобна подредба. Някои биха отбелязали, че не само липсата на квадратни и къдрави скоби би представлявала трудност да се програмира на JavaScript ползвайки Кирилица.

Yesterday, I shared a simple tool called Laravel Kickstart — a plain PHP file (configure.php) designed to help you spin up a new Laravel project quickly. It was a good start, but as I worked with it further, I realised something: while the idea worked, maintaining and extending it in plain PHP wasn’t going to scale well. So today, I’m excited to introduce the next step forward: KickOff — a fully‑fledge package! The transition wasn’t just a name change. KickOff represents a shift from a quick script to a structured, maintainable solution built for the long run. Yesterday’s Version Today’s Version Single plain PHP file (configure.php) Proper Laravel package structure Quick but hard to maintain Clean, modular, and extendable Manual adjustments needed Composer‑ready for easy installation Good for prototypes Ready for serious projects By refactoring the code into a package, it makes the code: Cleaner Codebase: Built using Symfony’s package conventions. Composer Support: Installable and autoloaded without hassle. Extensibility: Room to add more features like commands, config options, or integration hooks. Community Ready: Easier to share, collaborate on, and contribute to. The source code is now available here: https://github.com/cleaniquecoders/kickoff Installation and usage instructions are included in the repository. I’m planning to onboard some of setup from my Project Template. KickOff is all about giving your next Laravel project a smoother, more confident start — without the headache of maintaining messy setup scripts. If you tried the earlier version, I’d love for you to give KickOff a spin and share your thoughts!  ( 8 min )

The art of the soft launch is a welcome alternative to the hype and instant gratification of a world that too often is obsessed with new products, and services or even ideas. It is an approach that thrives on the understated, which gives the possibility of sharpening, evolving and creating a sense of anticipation that is natural as opposed to a single event and eventuality. A successful soft launch is anything but a happy accident or a low-key start, it is a carefully calculated move, aiming to make a splash and reduce the risks that the big reveal will cause.

As I continue my journey to become a better software craftsman, two insights from Martin Fowler and Uncle Bob stand out: Martin Fowler (Refactoring) "Any fool can write code that a computer can understand. Good programmers write code that humans can understand." Code is a shared language.

Uncle Bob (Clean Code) "The only valid measurement of code quality is how easily it can be understood and changed." Clean code isn’t just functional, it’s adaptable.

Their principles echo McConnell’s advice, writing code is half the job; crafting clear, human-friendly software is what makes us true cr…  ( 8 min )

I was recently tasked with writing tests for a large-scale production codebase serving over 2.1 million users. During my conversation with the lead engineer he mentioned something that stood out: “One of our biggest pain points is our test setup.” That conversation made me realize, that the approach I’ve been using might actually be more useful than I thought. This post walks through that setup. We mostly use PostgreSQL in production and write functional or integration tests, which means no database mocking. In the past, we relied on Testcontainers, to spin up real Postgres instances, but that approach was, slow and heavy.

Managing who can do what in an application is a fundamental challenge for developers. As your app becomes more complex and your user base grows, manually assigning permissions to every user becomes unmanageable and error-prone. Role-Based Access Control (RBAC) solves this by grouping permissions into roles and assigning roles to users. RBAC is one of the most widely used access control models. It enforces the principle of least privilege, simplifies admin tasks, and improves auditability. But "RBAC" isn't a single, monolithic concept. It's a spectrum of models, each suited for different needs. Choosing the right one is critical for building a secure and scalable application. What we'll cover RBAC Foundations: Core concepts and structure Hierarchical RBAC: Role inheritance and org charts …  ( 8 min )

CodeBoarding CodeBoarding is an open-source codebase analysis tool that turns large codebases into interactive, high-level diagram representations—so both humans and soon agents can understand them. Designed for onboarding, documentation, and system comprehension, CodeBoarding uses static analysis and LLM agents to map out your project’s structure, then turns that into diagrams you can embed in your docs, IDE, or CI pipeline. When I started programming, I remember spending hours drawing up diagrams for codebases just to understand the repo. Years later - I still find diagrams the best way to get a mindmap before diving into new code. So I built this (fully free) open-source project to generate those diagrams automatically. It summarizes repositories into simple, visual representations that you can explore at different levels of abstraction. Hope this helps. Please try it out and let me know what you think. Run CodeBoarding on your own repo: 🌐 www.codeboarding.org/demo Source code: 📄 www.github.com/CodeBoarding/CodeBoarding Control Flow Graph Extraction It starts with static analysis—extracting modules and their relationships based on control flow, not just import graphs. Multi-level Abstraction via LLMs CodeBoarding uses an LLM agent (provider-agnostic) to organize these into conceptual modules, abstractions, and summaries. Diagram Generation Outputs are rendered as Mermaid.js diagrams—interactive and embeddable in docs, IDEs, and web interfaces. MCP Integration (in progress) The generated representation can be served via a lightweight MCP server, allowing AI devtools (e.g., ClaudeCode, Cursor, VSCode agents) to query context-aware summaries and structure. Next steps Support more languages: Support for additional static-analysis friendly languages (e.g., Go, TypeScript, C++) is on the roadmap. Feedback on which to prioritize is very welcome! MCP Server: An MCP server is under development to allow your dev agents to use the overview for improved codebase indexing.  ( 6 min )

Hello, Dev Community! For the past couple of months, I've been on an incredible journey building something I'm truly passionate about. Today, I'm thrilled to take the first major step in sharing it with all of you. I'm talking about Project KARL (Kotlin Adaptive Reasoning Learner). What is KARL? Project KARL is an open-source library, built entirely in Kotlin, designed to create on-device, adaptive AI models. Instead of sending your data to the cloud to be processed, KARL learns and adapts exclusively on the user's device. It starts as a blank slate and becomes uniquely tailored to an individual's behavior over time. It's built on a few core principles: Action is Always Preceded by Learning In the spirit of that motto, I'm taking a docs-first approach to this release. I believe that for a project with a new architectural pattern to be truly understood and adopted, the concepts and guidelines must be clear from day one. Before you dive into the code, I want you to have the complete map. Today, I am officially releasing the complete documentation for Project KARL. This includes everything from high-level introductions and core concepts to detailed integration guides, API overviews, and contributor information. It’s the blueprint for the entire project. → Explore the Official KARL Documentation Here: KARL DOCS ↗ With the documentation now public, you can learn, explore, and understand the vision. The next step is action. The official open-source repository for Project KARL will be made public soon. On that day, you'll have access to the full source code for all the core modules, implementations, and the example desktop application that brings it all to life. The initial release will be an alpha version, a solid foundation ready for feedback, experimentation, and community contribution. It's the start of a journey, and I'm incredibly excited to build it in the open with all of you. So, take some time to read through the docs. Understand the "why" and the "how." And get ready to dive into the code. AR  ( 6 min )

This article answers the question: how to learn anything with neural networks without putting effort into writing prompts. At some point, the thought came to me that with the advent of neural networks, books have become obsolete. The "books" of the future are specially encoded knowledge inside neural networks. Learning should happen through dialogue with neural networks. In practice, it turned out that following such advice is quite difficult. Yes, you can go to a neural network and say "teach me calculus." The problem is that few people know how to ask the right questions. And those who do know understand that it's not simple in itself. The second problem is that a neural network is an assistant and advisor, but not a demanding teacher. It won't push you to expand your horizons. And as a…  ( 21 min )

Lessons from deep-diving JavaScript DOM with Satt Academy(website) 1. Node vs. Element: The Silent Speed Drain Code:- // Slow path (12% slower) const slow = parent.childNodes; // Grabs text & comment nodes // Fast path const fast = parent.children; // Only elements! Why care? 2. Live vs. Static Collections Code:- // Performance killer (live) const heavy = document.getElementsByClassName('item'); // Optimized path (static) const light = Array.from(document.querySelectorAll('.item')); 📉 Result: Live HTMLCollections cause up to 40% more browser reflows than static NodeLists — meaning slower, laggier pages. 3. Content Security Matrix innerHTML ❌ Not safe Slow Injecting trusted HTML textContent ✅ Safe Fast User-generated content createElement ✅ Safest Fastest Complex UI building ________________________________________ 4 Performance Optimization Should Use Event Delegation Code:- // 1 listener instead of 100 → Saves ~75% memory! parent.addEventListener('click', e => { if (e.target.classList.contains('btn')) handleClick(); }); Animation Mastery NodeList → Array Magic Code:- // NodeList looks like an array but isn’t const nodeList = document.querySelectorAll('.item'); // Convert for full array power const realArray = [...nodeList]; realArray.map(item => item.classList.add('processed')); Insights: 10,000+ Items? Virtualize! This simple step helps you write cleaner, faster, and more secure DOM manipulation code.  ( 6 min )

In the realm of React development, optimizing performance is a crucial aspect that developers constantly strive to enhance. One powerful tool in the React developer's arsenal is the useCallback hook, which plays a significant role in improving the efficiency of functional components. Let's delve into the intricacies of useCallback and how it can be utilized to boost performance. At its core, the useCallback hook in React is designed to memoize functions, ensuring that they are only re-created when their dependencies change. This can be particularly beneficial in scenarios where functions are passed down to child components, as it helps prevent unnecessary re-renders. const memoizedCallback = useCallback(() => { // Function logic here }, [dependency1, dependency2]); By specifying the dep…  ( 7 min )

Let's be honest - we all know that AI is evolving at an insanely fast pace. Earlier, it was just about writing specific prompts and getting basic outputs. But now, we have multiple advanced LLMs that are way more capable - they can even solve problems from the world's toughest exams like the JEE Advanced, USMLE, Bar, SAT, and more. What's even more interesting is the rise of AI agents - tools that can plan, reason, and complete multi-step tasks from start to finish. I can say that this is the beginning of a new era where agents can automate most of your time-consuming, repetitive work. And let's not forget prompt engineering, which has now become more like context engineering. Today's LLMs can write production-level code, debug it, and even help launch full-stack apps - all in minutes with…  ( 8 min )

As developers, we often build amazing tools, apps, or side projects — but getting traction is a whole different story. If you’ve ever wondered how to get more eyes on your project, digital marketing might be the missing link. Here’s how you can get started without becoming a full-time marketer. You wouldn’t build a product without user research, right? Apply the same mindset to marketing. Define: Who your product is for What problems it solves Where your audience hangs out online SEO (Search Engine Optimization) isn't just for bloggers. If your project has a landing page or blog: Use simple keyword research tools to find what people are searching for Optimize your content (titles, headings, meta descriptions) Create helpful blog content related to your app or tool If you're documenting your process, writing tutorials, or sharing case studies, you’re already doing content marketing. Use platforms like: Dev.to (yes, just like this!) Medium Your own blog Make sure to: Add internal links Include clear CTAs (call-to-actions), like joining your email list or trying the product Google still loves good backlinks. Writing helpful content (like this) and contributing to relevant conversations online can naturally earn links over time. 💡 I recently published a guide on best digital marketing resources website. If you'd like to learn more about digital marketing, feel free to check it out. Use tools like: Buffer or Hootsuite for social media Google Analytics for performance tracking Mailchimp or Buttondown for newsletters You don’t need to be a “marketer” to market your product. Just apply your developer mindset to experimentation, iteration, and measurement. Have you tried marketing your side project? What worked (or didn’t)?

Remote teams are growing, and so is the need for better communication across cultures. With teams spread across different countries, time zones, and native languages, understanding how languages interact is not just an academic topic—it’s practical and urgent. This is where the idea of cross linguistic connections becomes more than a linguistic curiosity; it becomes a tool for better collaboration, fewer misunderstandings, and stronger team culture. Cross-linguistic connections refer to the ways languages influence one another—whether through vocabulary, structure, pronunciation, or meaning. This can happen between individual speakers (like bilingual team members), or across wider cultural interactions. Think of it like this: if you've ever tried learning a new language and found that some…  ( 7 min )

Event bubbling is a fundamental concept in JavaScript that every web developer should master. It can make or break your event-driven applications if not handled properly. In this post, we'll dive into what event bubbling is, how it works, and how to control it using stopPropagation(). Let’s get started! In JavaScript, when an event (like a click) occurs on a nested DOM element, it doesn’t just trigger the event listener on that element—it bubbles up through its parent elements, triggering their listeners too. This behavior is called event bubbling. For example, if you have a div containing a ul with an li inside it, clicking the li could trigger event listeners on the li, ul, and div. This can lead to unexpected behavior if not managed correctly. Let’s look at a practical example to see ev…  ( 6 min )

Today I've learned that systemd, actually, supports hard reboots. systemctl reboot --force --force From the man page: If --force is specified twice, the operation is immediately executed without terminating any processes or unmounting any file systems. This may result in data loss. Note that when --force is specified twice the halt operation is executed by systemctl itself, and the system manager is not contacted. This means the command should succeed even when the system manager has crashed. This is the closest equivalent of echo b > /proc/sysrq-trigger I can find.  ( 5 min )
